Make the docker-compose test work rootless

Make sure the DOCKER_SOCK location is accessible by the user when run
rootless. Alos set the DOCKER_HOST env var to ensure docker-compose will
use the non default location. Cleanup steps such as `rm` or `umount`
must be run inside podman unshare otherwise they can fail due missing
privileges.

Change the curl test to use --retry-all-errors otherwise the tests will
flake. The web server inside the container will return http code 500
sometimes, most likely because it is not fully ready to accept
connections. With --retry-all-errors curl will retry instead of failing
and thus the test will work.
