I'm hoping this will address -> crbug.com/374490. +Tony for this!

Won't this get clobbered by the en-US.pak that is created by chrome_resources
since they both point to the same output file?  Why does the test apk try to
read locales/en-US.pak instead of locales/ui/en-US.pak.

We should probably split this into a separate change.

Tony, Chris, could this being caused by

From my understanding of
https://code.google.com/p/chromium/codesearch#chromium/src/ui/base/ui_base_pa...,
DIR_LOCALES on Android won't be out/Debug/locales/en-US.pak.
Yeah, I was thinking on that. The fix to the clobber issue on Android deserves a
separate CL.
