It would be a bit cleaner to add the timeout capability to the tst_rod
and pass timeout to tst_rod as a first parameter here. Which would fix
the second (below) that I have for this patch.

I do not like that we silently disable the timeout if 'timeout' command
is not available. I would rather add tst_timeout.c helper to the lib/ as
we do for instance for tst_sleep to support sub-second sleep intervals.
