installer: Make sure package manager state is preserved in the image

Package manager state should be preserved in the image as various
local features of the package manager may depend on this data to be
available. For pacman and zypper we already store local state inside
the image. For apt, we achieve this by storing all state in the image
by default except lists which is the repository metadata which we still
don't include in the image. For dnf/dnf5, we make sure the persistdir
points to inside the image.

Note that this state is still subject to removal by CleanPackageMetadata=
if the package manager is not installed or the option is explicitly enabled.

Fixes #3659
