ci: add testing via docker compose

Auto testing as well as good example on:
how to run SWTPM in docker or compose.

Simply run `docker-compose up` to bring both swtpm and test.
Or run `docker-compose up --build --force-recreate` to re-build.
Or run `docker-compose up swtpm` to only start swtpm service without
test.

Added new job in the github action to automate this as well.
