fix slirp4netns port forwarding with ranges
The slirp4netns port forwarder was not updated to make use of the new port format. This results in a problem when port ranges are used since it does not read the range field from the port. Update the logic to iterate through all ports with the range and protocols. Also added a system test for port ranges with slirp4netns, rootlesskit and the bridge network mode. Fixes #13643 Signed-off-by: Paul Holzinger <pholzing@redhat.com>
