safe-search: prevent duplicate cron job installation 

This patch prevents multiple cron jobs from being created to run the
safe-search-maintenance script.

To reproduce this bug, perform the following:
  - Install safe-search
  - Perform an OpenWRT firmware upgrade (choose to preserve user settings)
  - Install safe-search again
