[deps] Remove sourceMappingUrl from intl-messageformat

This CL removes the //#sourceMappingUrl magic comment from a third
party runtime dependency. It seems intl-messageformat as a slight
build missconfiguration in that it emits a sourceMappingUrl comment
but doesn't bundle the source map.

To silence console warnings for DevTools-on-DevTools, we can
omit the magic comment.
