rsyncrepo script: allow optionally supplying target name

The `rsyncrepo` and `rsynchydra` scripts now support an optional 3rd
argument to define the target name on the host instead of
auto-determining it from the basename.
This is important for syncing local directories of varying names all to
the same `fc-nixos` target for dev checkouts on VMs.
