Bug 14402: Add option --fees to /misc/cronjobs/cleanup_database.pl

Bug 14402: Add option --fees to /misc/cronjobs/cleanup_database.pl

This will call C4::Accounts::purge_zero_balance_fees to remove all rows
from accountlines which have 0 balance, and are more than DAYS old.

Test plan:

  Run: t/db_dependent/Accounts.t

If all unit tests pass, the --fees option to /misc/cronjobs/cleanup_database.pl
should act as documented, because it is a straight pass-through to
C4::Accounts::purge_zero_balance_fees().
