Run the daily catchup rsync before the daily indexing catchup cronjob

Otherwise missed files won't get indexed since they won't exist until
the rsync runs.

This also gets rid of the random sleep because it a) didn't work under
/bin/sh (really /bin/dash) since $RANDOM is a bash-ism and b) isn't
necessary anymore since our cronspec is no longer 04:40 as suggested in
the cpan.org example.
