Martin Roth 31e0d42a1d util/lint: Run lint-extended-007-final-newlines checks in parallel
Instead of checking each directory in series, kick off the checks
in parallel and then wait for them to finish.  Failures print out with
file information, so mixing output isn't a problem.  This reduces
the time it takes to run on lumberingbuilder by 60%.

This could probably be sped up even more by splitting up src/mainboard
into smaller sections.

This method does skip a few control files at the top level - .gitignore,
.checkpatch.conf, gnat.adc, etc.  These could be added to the list of
files to check, but I didn't think it was needed.
