I don't think we need this function anymore. Particularly it makes little sense
to check that path exists before running it. It's better to just try running the
binary and handle the error if exec() or system() fails.

Removed. I slightly tweaked the logging in one of the places where it was
called, so that we see the path logged before subprocess.Popen throws.
