Revert "remote: Add libvirtd dependency to virt-guest-shutdown.target"

Further testing revealed commit f035f53baa regresses Debian bug 955216

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=955216

Restarting libvirt-guests on libvirtd restart is worse than the original
dependency issue, so revert the commit until a better solution is found.

This reverts commit f035f53baa2e5dc00b8e866e594672a90b4cea78.
