Simplify test locales in Mac's ui_unittests Framework (take 2)

Simplify test locales in Mac's ui_unittests Framework (take 2)

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 repack the
strings made for ui_test.pak to en.lproj/locale.pak and roll it into the
mini-framework bundle.

Note we can't simply copy ui_test.pak because Mac system libraries will
annoy valgrind with leaks when they encounter unexpected things in it.

Hi Avi, it's take 2 - please take a look. I've tested locally on my Snow Leopard
machine with valgrind to ensure the issues are gone. Thanks!

For clarity, those issues: valgrind was picking up leaks from allocations within
system libraries when trying to use all of ui_test.pak. Fix: rebundle with just
strings. Patchset 1 has the earlier CL, so you can diff against that to see
changes.
