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):

    OBJECT = object_dict['port'](args)

v5: fix from Petr Lautrbach
v4: keep types found with attribute port_type for compatibility with types
    which are not portcons
v3: use even better version, thanks to Petr Lautrbach
v2: fix other cases and use better version courtesy of Petr Lautrbach
