Bug 38053: Change description of DefaultLongOverduePatronCategories and DefaultLongOverdueSkipPatronCategories system preferences

This patch changes the description of the DefaultLongOverduePatronCategories
and DefaultLongOverdueSkipPatronCategories system preferences
to make it clearer it has to do with the **long overdues** process
and not just the overdues process. It also highlights the
warning by making it bold.

To test:
1. Apply patch
2. Go to Administration > System preferences > Circulation >
   Lost item policy
3. Read the description for DefaultLongOverduePatronCategories
   and DefaultLongOverdueSkipPatronCategories, make sure it
   makes sense, that the grammar and spelling is OK
