quiet_system: Dump to /dev/null instead of closing
Some programs fail where they would otherwise succeed if stdout or stderr is
closed. For example, using mpicc from the mpich2 formula:
quiet_system 'mpicc', '--version'
Fails with:
LLVM ERROR: IO failure on output stream.
While
system 'mpicc', '--version'
Succeeds.
Closes #13253.
