Do not set host IP on ports when 0.0.0.0 requested
Docker and CNI have very different ideas of what 0.0.0.0 means.
Docker takes it to be 0.0.0.0/0 - that is, bind to every IPv4
address on the host. CNI (and, thus, root Podman) take it to mean
the literal IP 0.0.0.0. Instead, CNI interprets the empty string
("") as "bind to all IPs".
We could ask CNI to change, but given this is established
behavior, that's unlikely. Instead, let's just catch 0.0.0.0 and
turn it into "" when we parse ports.
Fixes #7014
