android_webview: roll AOSP bot manifest.

android_webview: roll AOSP bot manifest.

Update to a recent version of AOSP master. The primary effect on
Chromium is that the android_aosp bot will now use a recent version of
clang when building chromium targets for host and thus we no longer need
to support using gcc 4.2 or 4.6 to compile host code here.

Marcin, when you're back lets make sure the process for rolling this is written
down somewhere.
