Bug 34868: Add ability for SIP2 to distinguish missing item from other lost types

Bug 34868: Add ability for SIP2 to distinguish missing item from other lost types

The SIP circulation status specifies that a 12 means an item is lost, and 13 means an item is missing. In Koha, missing items are simply a type of lost item so we never send a 13. This is an important distinction for some SIP based inventory tools. It would be good to be able to specify when lost status means "missing" at the SIP login level.

Test Plan:
1) Apply this patch
2) prove t/db_dependent/SIP/Transaction.t
