Drop copying qemu binaries and ensure qemu-user is configured on host

Since Mageia 6, it has not been necessary to copy the qemu binaries
and the binfmt files into the chroot to run ARM binaries inside a chroot.
This change finally stops doing that.

In order to make sure this works properly, we ensure that systemd-binfmt
is restarted to apply binfmt changes on the system. This ensures that
the host qemu-user-static is configured to execute binaries, even in
chroots.
