Create ssync-reapr to clean up ssync run files

ssync-reapr will delete the run files pushed to the ssync output
dir (default ~/.local/share/ssync/runs/) which can accumulate over
time. The default is to only delete files older than a day.

We run the reap as the first step of every ssync - to ensure it clears
out the necessary files
