Reviewed by Jonathan Bedard.

Remove the hack that relied on the existence of an internal
unittest.TestProgram.USAGE package variable, and instead just
print out our custom help message first.  (The reason the
internal variable was used was to make the custom help text to
look like it was integrated nicely with the default help text.)

We can't print our custom help message last since the package
exits early when a help switch is passed.

* Source/WebKit/Scripts/webkit/messages_unittest.py:
- Import print_function from __future__ to make the script work
  with python2.7.  Unit tests are still run with both versions.
(add_reset_results_to_unittest_help): Delete.
(parse_sys_argv):
- Print our custom help text if a help switch is used.
