Subject: [PATCH] Use //# instead of //@ for sourceMappingURL comment

Summary:
I had an issue debugging in chrome 48 on windows where source maps didn't work. I tried changing the sourceMappingURL comment to use the //# syntax instead and it fixed the problem.

According to https://developers.google.com/web/updates/2013/06/sourceMappingURL-and-sourceURL-syntax-changed?hl=en the //@ syntax was deprecated for //#.
Closes https://github.com/facebook/react-native/pull/4892
