[PATCH 14/11] v2writable: replace: kill git processes before reindexing

["Eric Wong (Contractor, The Linux Foundation)" <e@80x24.org>]

Xapian on Linux <3.15 has trouble with coprocesses since it used
fork() for locking and would hold onto pipes used for git
unnecessarily.
---
 I'm not sure if this fixes a problem, actually; but it's a
 general cleanliness thing and we already have convuluted logic
 in the SearchIdx.pm code for v1 to deal with the same thing.
