ci/android: add android to the ci

Add android to the ci, so we can test mesa on it.

Add debian/x86_test-android and test-android jobs.
One build the container to run tests, and the other execute the tests.

Android is executed on top of cuttlefish VM with virgl.
Mesa libs are replaced on the cuttlefish image, and deqp and deqp-runner
are used to execute tests.
