Bug 12943 - Add patron branchcode to patron search results for holds

For some libraries, the current information specified in the patron
results when search for a patron to place hold is insufficient. These
libraries would like the branchcode to be added to the results to help
identify the correct patron.

Test Plan:
1) Apply this patch
2) Browse to the holds for a record
3) Search for patrons from the record holds screen
4) Note the patron results now have the branchcode after the patron type
