In the relaxed sandbox, we want to run executables frome everywhere

outside /usr doesn't depend (heavily) on what's in /usr and if it does
and a tools tree is used it should match the host sufficiently.

Parse profiles in subimages as well
Let's parse from mkosi.profiles in subimages as well. We'll still insist

we have to remove the check to see if a profile exists or not, since it might
not exist in every mkosi.profiles/ directory that we parse. At the same time
we remove the restriction that profiles are set before we parse mkosi.conf.d/
since this isn't really useful anymore now that we parse profiles last and not
first anymore. This allows us to get rid of the concept of immutable settings.

Wait until sandbox exec()'s specified command before continuing
Let's wait in spawn() until all setup logic has completed before
continuing if a sandbox is used. When using spawn() without run(),
this helps us fail early if the setup logic fails instead of later

afterwards.
As a side effect, this also acts as a synchronization point when using
systemd-run --scope where when spawn() returns, we can be 100% sure that
the scope has been created, which is important when calling RegisterMachine
from systemd-machined which does the wrong thing if the scope for the specified
machine does not yet exist and ends up killing the parent unit (often the user

Run binaries from ExtraSearchPaths= within tools tree
Until now, there was always the implicit assumption that any paths
configured with ExtraSearchPaths= contained binaries built against
the host's /usr. With that assumption, it made sense to execute binaries
found in these paths outside of the tools tree as otherwise you might
end up with missing or out of date libraries if these are not available
within the tools tree.
However, with the introduction of "mkosi sandbox", what I want to do
in systemd is to have contributors build systemd within the sandbox and
then use those binaries in mkosi to build the image. This means that the
build directory configured with ExtrasSearchPaths= suddenly contains
binaries built against the tools tree's /usr (if one is configured) instead
of the host's /usr.
Given this new use case, let's get rid of the logic to not use the tools
tree for binaries in ExtraSearchPaths=, instead, users of ExtraSearchPaths=
using a tools tree will have to make sure to use a tools tree that mostly
matches their host's /usr.

Drop PEAddons=
Putting these inside the image isn't very useful except for the very
specific use case of being able to skip copying the addon when copying
the ESP to another disk to implement a "live" installer mode. For all
other use cases, PE addons are either supposed to be generated locally
or optionally downloaded alongside the image. For these use cases it
makes much more sense to output the addons alongside the image, but not
in it.
But if it makes more sense to output the addons alongside the image, then
it becomes unclear whether this is something that should be implemented inside
mkosi in the first place. Until we figure whether this makes sense and how
to implement it, let's remove the functionality.
Addons can still be added to the image or generated alongside it by running
ukify in a postinst script. The secure boot signing options will have to be
passed manually but this isn't an unsolvable problem.
