Delete build directory (mostly).

To streamline our build, I've gone through
and eliminated the redundant build directory.
Strings in build/res have been moved into the
regular res/ directory and the
file has been updated to no longer use the
non-existent build directory at all. Fixes b/9105428.

Unfortunately, one src file has to be in build to
make the open source/closed source builds work
properly since we don't have src overlays in the build.
