Fix babel only regexp on windows

Browse Source 
Summary:
cli / packager was broken on Windows after 28f1c67ced5f082d92ba674e7e8bd233f4ff29ca.

Babel `only` regexp option requires paths to use forward slashes only but `__dirname` will use backslashes on windows. This simply adds a replace to normalize to forward slashes.
