mkarchroot: Use systemd's nspawn if available
* If we are running systemd use nspawn instead of our own chroot setup * Use pacstrap to setup our chroot environment * Make sure the common trap is still called * Bind resolve.conf, timezone and lcoaltime from the host if nspawn is not used * Run ldconfig within the chroot
