Repair too-timid hold targeter (it misses copies at other org units)

The patch to address bug 1162989 overreached.  Whereas before that
patch, the hold targeter was wont to target copies with unholdable
statuses, after the patch the hold targeter got the statuses right but
undesirably filtered out copies whose circ_lib doesn't match the hold
pickup lib.  This again probably stems from the differences between
FulfILLment's hold targeter and Evergreen's in the context of merging
the calculated proximity code.

This patch should resolve the issue.
