Settings: Comment out Google's bug report

This really feels out of place and does not serve a purpose in OmniROM or any custom ROM really.
On top of that, I doubt Google would seriously take into consideration a bug report off a custom
ROM.

I also think it confuses your average user when they try to submit a report via that option and
nothing happens....
