Jan Zarsky 1791cb42fc libsemanage: test semanage_ibendport_* functions 
Add new test suite for semanage_ibendport_* functions. The test suite aims for
line coverage and covers expected usage of functions. The test suite uses custom
semanage store and policy written in CIL, it does not require running on SELinux
enabled system.
