Bug 1365419 - Fixup l10n packager after bug 780562. r=gps

The change to l10n packager from bug 780562 worked in practice because
no chrome category had exclusively manifest entries with flags, which
we're changing in this bug.

It turns out this was only due to a missing change in the patch for bug
780562.
