Summary: Add some basic unit tests for extutil.runbgcommand(). This also changes the behavior to throw an OSError if we fail to execute the process, instead of a subprocess.CalledProcessError. This matches the behavior of the subprocess module when it fails to execute the command. Test Plan: Ran the tests.
