res_pjsip_config_wizard.c: Add port matching support.

In f8b0c2c9 we added support for port numbers in 'match' statements
but neglected to include that support in the PJSIP config wizard.

The removed code would have also prevented IPv6 addresses from being
successfully used in the config wizard as well.
