To allow for fault injection of the virCommand dry run,
add the ability to register a callback. The callback will
be passed the argv, env and stdin buffer and is expected
to return the exit status and optionally fill stdout and
stderr buffers.
virCommandProcessIO should be skipped on a dry run, since it overwrites the
buffers.
