Setting the uid/gid of the child process was the only thing done by
the hook function in this case, and that can now be done more simply
with virCommandSetUID/GID.

Change from V1: rebased.

Back to my argument in 4/15 - it looks funny to see
virQEMUCapsProbeCommand taking two arguments, just to call into two
virCommandSet* calls with one argument, just to be combined back into
virSetUIDGID with two arguments.  But again, I'm not going to insist on
a respin for a cosmetic difference.

ACK still stands.
