Fix a few gpu tests on Android

Make GpuProcess.driver_bug_workarounds_upon_gl_renderer work on Android.

For other tests it does not make sense to run them on Android because
there is either no entry in kSoftwareRenderingListJson to trigger
or no multi gpu configuration.

About GpuProcess.skip_gpu_process, I could not reproduce the failure on
Nexus 4.
