runlabel: run any command
As discussed [1], the runlabel command should execute any command specified in a label. The reasoning behind is that we cannot restrict which options are passed to Podman which thereby has full access to the host (runlabels must be used with care). With the updated semantics, runlabel will substitute the commands with a basepath equal to "docker" or "podman" with "/proc/self/exe", and otherwise leave the command unchanged to execute any other command on the host.
