make_dist_tarball: check for a dirty source tree

Have the make_dist_tarball script check to ensure that the source tree
is clean before continuing.  This ensures that we don't accidentally
build a distribution tarball with something that is not committed in
the repo.

There is a --dirtyok option to override this check, and if you access
this script via the "make_tarball" link, --dirtyok is added to the
default set of options.

Cleanup a race condition regarding marking that waitpid_fired. We should always mark it as fired when we enter the wait_local_proc routine, and also mark it as no longer alive if iof_complete has also been found. If other places in the code also update those flags, there is no harm done.

Update the regex to resolve a bug
Nathan had requested this before as he needs to know the #procs in the job to optimize the UGNI btl. Add the fetch for that data - the native pmix component already provides it, but ensure the Slurm PMI-1 support does too. If not found, fall back to the non-optimized number
