Wrap calls to main() with if check

A change was merged to the main Ansible core code that can cause

a potential hang if any libraries are called that use threading.

This change was:

  4b0aa1214c

This affected the os_object module by causing a hang on the shade

create_object() API call (which in turn calls swiftclient which

uses threading). The fix is to make sure all modules have a main()

that is wrapped with an "if __name__ == '__main__'" check.
