mkosi: Use build/ as extra search path by default

Building systemd with mkosi generally requires a very recent version
of systemd which might not be installed on the host. Let's configure
mkosi to look for extra executables in the build/ directory by default
so that we prefer systemd executables from the build directory over those
on the host as those on the host are likely to be too old.
