semanage, sepolicy: list also ports not attributed with port_type

For `semanage port -l` and `sepolicy network -t type`, show also ports
which are not attributed with `port_type`. Such ports may exist in
custom policies and even the attribute `port_type` may not be defined.

This fixes the following error with `semanage port -l` (and similar
error with `sepolicy network -t type`):

Traceback (most recent call last):
