improve slirp4netns allow_host_loopback docs 

The default ip is 10.0.2.2 but is always the second ip from the
slirp4netns subnet, which can be changed via the cidr option.

Fixes https://bugzilla.redhat.com/show_bug.cgi?id=2090166

- **slirp4netns[:OPTIONS,...]**: use **slirp4netns**(1) to create a user network stack. This is the default for rootless containers. It is possible to specify these additional options, they can also be set with `network_cmd_options` in containers.conf:
- **allow_host_loopback=true|false**: Allow the slirp4netns to reach the host loopback IP (`10.0.2.2`). Default is false.
- **allow_host_loopback=true|false**: Allow slirp4netns to reach the host loopback IP (default is 10.0.2.2 or the second IP from slirp4netns cidr subnet when changed, see the cidr option below). The default is false.
- **mtu=MTU**: Specify the MTU to use for this network. (Default is `65520`).
- **cidr=CIDR**: Specify ip range to use for this network. (Default is `10.0.2.0/24`).
