Check in the pre-built ICU data files for Android

- Update brkitr.patch to apply to ICU 52. ICU 52 has the CJK segmenter
  built-in. Fortunately, we just have to change the brkitr data without
  touching the code.
- Update patch_locale.sh for additional data trimming (calendar and
  zone - exemplar cities).

- Apply the two patches locally (the result is not landed in the tree) and
  build the icu data (icudtl.dat and icudtl_dat.S).

The size of icudtl.dat with zip compression increased by
125kB (1,998,805 vs 1,870,219) and the uncompressed icudtl.dat got bigger
by 463kB (6,049,360 vs 5,575,648)
