mkosi: use apt pinning for locally built debian/ubuntu packages

This ensures that even in case the distro repository has newer
versions, the locally built packages are preferred and installed,
even to the point of downgrading already installed ones.
This is needed especially for future stable branches, when the
distros will have a newer version.
