Remove noisy NOTIMPLEMENTED in audio_manager_base.cc

This is NOTIMPLEMENTED is reached and printed in browser tests, and
just adds noise. Since browser tests are using this method, it seems that
overriding it is not a requirement, so remove the NOTIMPLEMENTED.

Revert 248285 "Roll DEPS for gtest library."

The Android bots are exploding, failing every test.

http://build.chromium.org/p/chromium.linux/builders/Android%20Tests%20%28dbg%29/builds/18272
http://build.chromium.org/p/chromium.linux/builders/Android%20Tests/builds/11653

That is highly unusual behavior, so I'm blaming the DEPS roll for the test library for now.
