polkit: remove rsync build dependency

Browse Source 
It the polkit post-install, the files that are supposed to live under /etc and
/run/current-system/sw/share have to be merged into the package at the correct
location. Previously, rsync was used for this job. By being a bit careful about
the ordering, it is possible to use plain mv instead. The main advantage is
that the number of transitive reverse dependencies of rsync is reduced
significantly, so rsync changes will no longer need to go through staging.
