The android emulator launcher script is mainly used in CI and thus
makes sense to be moved there. This also makes it easier to make changes
without having to wait for submodule updates.
ANDROID_EMULATOR_RUNNER is defined in qt5's Android provisioning script.
Also, change the order of instructions execution to set COIN_CTEST_RESULTSDIR
env variable before running the emulator script. That var points to the path
to where the emulator logs are saved.
