git: improve coupling with {sock} and {inflight} fields

While the {inflight} array should be tied to the IO object even
more tightly, that's not an easy task with our current code.  So
take some small steps by introducing a gcf_inflight helper to
validate the ownership of the process and to drain the inflight
array via the awaitpid callback.

This hopefully fix problems with t/lei-q-save.t (still) hanging
occasionally on v2 outputs since git->cleanup/->DESTROY was getting
called in v2 shard workers.
