[PATCH] Run docker probe only if docker or podman are available

[Stefan Weil]

The docker probe uses "sudo -n" which can cause an e-mail with a security 
warning
each time when configure is run. Therefore run docker probe only if either 
docker
or podman are available.

That avoids the problematic "sudo -n" on build environments which have neither
docker nor podman installed.
