avoid limited space of random temp file names if clock resolution is low
this is not an issue that was actually hit, but I noticed it during
previous changes to __randname: if the resolution of tv_nsec is too
low, the space of temp file names obtainable by a thread could
plausibly be exhausted. mixing in tv_sec avoids this.
