Bug 25958: Allow LongOverdue cron to exclude specified lost values

Bug 25958: Allow LongOverdue cron to exclude specified lost values

When lost items are not marked as returned, they are still subject to
the long overdue cron, so an item that has already been marked Lost may
automatically roll to Long Overdue. In some cases, a library may not
want that lost value to change. This becomes especially important with
the introduction of Claims Returned, which uses a variety of lost.

Test Plan:
1) Set up a long overdue item that would be moved to lost by longoverdue.pl
2) Run the cronjob with the new --skip-lost-value option
3) Note the item is not altered
4) Include that value in the new system preference DefaultLongOverdueSkipLostStatuses
5) Run the cronjob *without* the new option
6) Note the item is not altered
7) Run the cronjob again with the new command line option, but set it to
a different value so the item will be affected
8) Note the item is altered as it would have been before this patch was
applied
