Check in the pre-built ICU data for Android

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)

Can you take a look? (I'll update TEST line). 

I tried hard to minimize the size increase, but couldn't make it as small as
before. 

The size increase is about the same as the size of Khmer and Lao dictionaries
that are critical in the correct line breaking for those languages (in web
pages).

BTW, don't be confused by 'icu52.android' in the path. This change will get
landed in svn://svn.chromium.org/chrome/trunk/deps/icu52. （I don't know why
codereview/gcl upload prepend the path with 'icu52.android' (my local directory
name)).

LGTM. I have some errata to add for the instructions in the README, but I need
to look them up and land them separately.

Thanks for updating.
