Fix some android configuration

Fix some android configuration

This adds //chrome/test:test_support_unit to the root build targets for
Android. This target is used by downstream things and so adding it to
the root will ensure that it is buildable upstream. This requires making
the sync integration/performance stuff be not defined if !is_android
(since they depend on things that aren't defined on that platform).

Changes the internal configuration hooks to not require setting the sdk
information.

Makes unittest_apk actually forward datadeps.

Ugh, Rietveld diff for everything below this is ugly.

`git diff -b` properly shows it as just an indentation.
