content_gl_tests were failing because, we are checking for rgb565 platform support
on hardware and failing intentionally, which was not correct, the test should be skiped instead. This patch takes care of that along with the base patch.
On Aura with Nvidiea drivers the support is not there, so the test fails previously now weare skipping it by displaying the reason.
Android the support gets passed.
