Fix OperationSystemVersion() on Android.

Right now it returns the underlying kernal version instead of the Android version.

However, OperatingSystemVersionNumbers returns the Android version.

Per discussion with Android folks, we agree the Android version should be returned.

This CL copies what we do for Mac version.

This piece of information could be very useful in defining driver bug workarounds in a finer grid on Android.
