i9300: audio: bring back removed microphone fix

http://review.cyanogenmod.org/61104 has reverted http://review.cyanogenmod.org/51085
which has bought back issues with microphone after a voice call. After a voice call,
the microphone is either not working or the recorded audio is very faint and not
audible.

The Input device has to be explicitly set to AUDIO_DEVICE_NONE after a voice call,
since force_all_standby() wouldn't work for a voice call usecase.

More details about the fix is included in the gerrit comments for the actual patch.

Switch back to the binary camera HAL

Add compatibility libutils symbols required by it, and use it
again. It's much more reliable than the reimplementation
