tools, scripts: refactor error-out statements of Python scripts
In Python, sys.exit() function can also take an object other than an integer. If an integer is given to the argument, Python exits with the return code of it. If a non-integer argument is given, Python outputs it to stderr and exits with the return code of 1. That means, print >> sys.stderr, "Blah Blah" sys.exit(1) is equivalent to sys.exit("Blah Blah") The latter is a useful shorthand. Note: Some error messages in Buildman and Patman were output to stdout. But they should go to stderr. They are also fixed by this commit. This is a nice side effect.
