Two things before this CL was wrong:
* The script didn't apply paches
* The patch we needed to apply wasn't applied because a dart roll in the
engine was done basically at the same time that the change requiring
the patch was landed. The dart-roll did not include it, but the change
applied the patch the the before-dart-roll-dart-version.
This CL fixes it by applying patches in the flutter-frontend script,
and copying the patch to apply to both dart-revisions.
