semanage/test-semanage.py: Return non-zero value when some of unittes…

…t tests fail

Previously python/semanage/test-semanage.py returned 0 even when there was a
fail in some test and `make test` didn't indicate any problem.

Fixes:
    $ make test
    ...
    Ran 10 tests in 110.854s
    FAILED (failures=4)
    $ echo $?
    0
