podman: make docker wrapper configurable via packageconfig

Browse Source 
podman can behave as transparent drop in replacement for docker
via a wrapper 'docker' script that simply calls podman when any
docker command is issues.

While this is an interesting feature, we want it to be optional
.. since it is possible that podman and docker might want to be
installed at the same time.

So we introduce a 'podman' PACKAGECONFIG, that controls whether
or not this wrapper is installed, and if it is installed it marks
the podman package as conflicting with docker (which gets us a
better message than a failed image assembly provides).
