validation: Test futex support

The test source code is generated from specification items
by the "./spec2modules.py" script contained in the
git://git.rtems.org/rtems-central.git Git repository.

Please read the "How-To" section in the "Software Requirements Engineering"
chapter of the RTEMS Software Engineering manual to get more information about
the process.

Update #3716.
