virCommandTransferFD promises that the fd is no longer owned by

* src/util/command.c (virCommandTransferFD): Close fd now if we
can't track it to close later.
(virCommandKeepFD): Adjust helper to make this easier.

This leak can only happen on OOM or other extreme error conditions,
but ought to be plugged. When I originally posted this:
https://www.redhat.com/archives/libvir-list/2011-July/msg00674.html
DV was worried that callers might abuse things and use fd
even after this function closed it; but I proved to myself in
writing a (non-working) v2 that all callers were already safe,
and that this v1 was indeed a smaller solution.
Okidoc then :-)
ACK,
Thanks; pushed.
