ci/android: add a job using android-cts instead of deqp-runner

We also want to run Android CTS in the Android jobs.

Since the Android CTS is quite large, download it and strip it down to
only contain the interesting tests, so to reduce the space taken in the
container image.

Eventually we might want to have android-cts be run via deqp-runner
itself, but for now add a proof-of-concept mechanism which calls the
android-cts directly and uses an ad-hoc handling of expectations.
