scripts: ensure not specifying subcommand shows help textpaule/devtool17-oe

With Python 2, argparse subparsers behaviour in Python 2 was to print
the usage information if the subparsers argument wasn't specified.
However, with Python 3.2.3 and later a subparsers argument is not
required by default, leading to errors when no arguments are specified:

  AttributeError: 'Namespace' object has no attribute 'func'

Restore the previous desired behaviour of showing the help text for
devtool, recipetool and the devtool-stress script by setting
subparsers.required to True.
