wic: Check for external modules
Since eight unique files import rpm, perform a check at the top level for the existence of the rpm module print a sensible error message if it is not. This may be able to be removed if some of the core rpm dependencies are removed from the mic libs. Also check for urlgrabber. This avoids a bracktrace in the event the modules are not installed which can be very off-putting to would-be users.
