Run recipe tests using UML on GitHub actions

Running the tests on the host is a good first step; to test Debos properly we should run inside a Fakemachine. Since GitHub actions do not support creating nested virtual machines, use the user-mode-linux backend in Fakemachine to create a user process to run the tests inside of. Since Docker autobuild does not support UML the docker-compose file purposely does not have a suffix of `.test.yml` so that the test will not be picked up to run on Docker autobuild.
