port_handler=slirp4netns not publishing multiple ports anymore

/kind bug

Description

Using port_handler=slirp4netns to preserve the src IPs, podman v4.0.2 does not publish multiple ports anymore, only the first port seems to be forwarded. On v.3.4.4, publishing multiple ports does work.

Steps to reproduce the issue:

1. podman run -p 2379-2380:2379-2380 --network slirp4netns:port_handler=slirp4netns -it alpine /bin/sh

2. verify open ports, e.g. using netstat -tnl | grep :23

Describe the results you received:

tcp 0 0 0.0.0.0:2379 0.0.0.0:* LISTEN 1024868/slirp4netns

Describe the results you expected:

tcp 0 0 0.0.0.0:2379 0.0.0.0:* LISTEN 1024868/slirp4netns
tcp 0 0 0.0.0.0:2380 0.0.0.0:* LISTEN 1024868/slirp4netns

Additional information you deem important (e.g. issue happens only occasionally):

podman ps correctly shows: 0.0.0.0:2379-2380->2379-2380/tcp

It works on podman 3.4.4
