Update Android to use Compact Language Detector v2.

Update Android to use Compact Language Detector v2.

Android is the last remaining platform that has not yet converted to CLDv2.
Sheriffs: expect to see APK size changes in the range of [-122K, +98K] bytes.
See the bug for more information.

As on iOS, use the smallest data tables to minimize the binary size impact.
This brings language detection on Android into parity with iOS (which also uses
the smallest data tables).

Posterity: linux_chromium_rel_ng failure is spurious and due to some kind of
filesystem error with language packs.
