Revert of Simplify test locales in ui_unittests Framework

Revert of Simplify test locales in ui_unittests Framework (patchset #1 id:1 of https://codereview.chromium.org/552963002/)

Reason for revert:
Bizarrely, this is causing valgrind on Snow Leopard to pick up a
bunch of leaks from allocations within system libraries.
Reverting while I figure out how best to fix that.

BUG=413034
Original issue's description:
> Simplify test locales in Mac's ui_unittests Framework
>
> Mac creates a mini-framework in `ui_unittests Framework` so that ui
> tests can get a resource bundle without depending on the Chrome
> framework.
>
> The way it generated locale information was causing build flakes since
> two instances of repack_locales.py could be writing to
> out/../gen/repack. Tests always use en-US, so instead just do what iOS
> does and copy ui_test.pak to en.lproj/locale.pak and roll it into the
> mini-framework bundle.
