Bug 21953: Term 'Lost item' untranslatable

This patch removes the hardcoded untranslatable string
'Lost item' from C4/Circulation.pm.

To test:
1) Make sure the system preference WhenLostChargeReplacementFee is set to Charge
2) Optional: in Administration > Item types, add a default replacement cost to
the item type you plan to use
3) Loan an item out to a patron
(If there is no default replacement cost, make sure the item has a replacement
price)
4) In the patron's account > Details > Loans, click on the item's barcode
5) Set the lost status to Lost
6) Go back to the patron's account > Fines
7) Notice it is written 'Lost item , Lost item title barcode (title)'
8) If you have another language installed, switch to the other language
and notice the second Lost item is still in English
9) Apply the patch
10) Redo steps 3-6
11) Notice it is written 'Lost item, title barcode (title)'
12) Optional: switch to another language, notice there is no English string
