[PATCH 2/3] python: use == or != when comparing a variable with a string or a integer

[Nicolas Iooss <nicolas.iooss@xxxxxxx>]

Flake8 3.7.0 added a new fatal error message when parsing Python files:

    python/semanage/semanage:112:16: F632 use ==/!= to compare str, bytes, and int literals
    python/semanage/semanage:124:23: F632 use ==/!= to compare str, bytes, and int literals
    ...
    python/sepolgen/src/sepolgen/output.py:77:8: F632 use ==/!= to compare str, bytes, and int literals
    python/sepolgen/src/sepolgen/output.py:80:8: F632 use ==/!= to compare str, bytes, and int literals
    python/sepolgen/src/sepolgen/output.py:83:8: F632 use ==/!= to compare str, bytes, and int literals
    python/sepolicy/sepolicy/generate.py:646:16: F632 use ==/!= to compare str, bytes, and int literals
    python/sepolicy/sepolicy/generate.py:1349:16: F632 use ==/!= to compare str, bytes, and int literals

Fix all these warnings.
