[PATCH 12/16] lei_xsearch: ensure curl.err and tail(1) cleanup happens

[Eric Wong <e@80x24.org>]

We can safely rely on exit(0) here when interacting with curl(1)
and git(1), unlike query workers which hit Xapian directly,
where some badness happens when hit with a signal while
retrieving an mset.
