MFC r227013:

1. Add a new option, --run-updates, to always or never run the newalises,
   pwd_mkdb, etc. updates at the end of the comparison.

2. Add an update to the end to handle /etc/localtime, if it exists.
   If /var/db/zoneinfo exists, automatically update /etc/localtime,
   which should (hopefully) be safe to do. If not, prompt the user
   to run tzsetup.

3. Update run_it_now(), the function that handles input for the updates,
   to make sure that we got a valid answer, and to handle the --run-updates
   option if supplied.
