Execute /proc/self/exe instead of podman. This makes the runlabel
command more portable as it works for binaries outside the path as
well as for local builds.
Also, avoid redundantly executing the runlabel command by setting
the PODMAN_RUNLABEL_NESTED environment variable to "1". Podman
now checks for this variable before executing the runlabel command
and will throw an error in case the variable is set.

Execute the command as described by a container image. The value of the label is processed
into a command by:
1. Ensuring the first argument of the command is podman.
2. Substituting any variables with those defined by the environment or otherwise.
If no label exists in the container image, nothing is done.
podman container runlabel LABEL IMAGE extra_args
