Update {virtual,override,final} to follow C++11 style.

Update {virtual,override,final} to follow C++11 style.

The Google style guide states that only one of {virtual,override,final}
should be used for each declaration, since override implies virtual and
final implies both virtual and override.

This patch was automatically generated with an OS=android build using a
variation of https://codereview.chromium.org/598073004.

While I'm an OWNER of media/ and love this CL (and the auto-fixit CL), there are
more specific owners of each of these files than myself.

I suggest:
tommi@ per media/audio/OWNERS
qinmin@ per media/base/android/OWNERS
one of the three media/midi/OWNERS
one of the four media/video/capture OWNERS
