ResourceLoader::makeLoaderImplementScript: Bind args as '$' and 'jQuery'

Make the function that wraps ResourceLoader modules bind the first and
second arguments it receives to '$' and 'jQuery'. This patch is a
follow-up to change I0c9edac35, which updated the invocation of
mw.loader#implement so that it passes jQuery as the first and second
argument.
