Vit Mojzis 344463076b gettext: handle unsupported languages properly
With "fallback=True" gettext.translation behaves the same as
gettext.install and uses NullTranslations in case the
translation file for given language was not found (as opposed to
throwing an exception).

Fixes:
  # LANG is set to any "unsupported" language, e.g. en_US.UTF-8
  $ chcat --help
  Traceback (most recent call last):
  File "/usr/bin/chcat", line 39, in <module>
    t = gettext.translation(PROGNAME,
  File "/usr/lib64/python3.9/gettext.py", line 592, in translation
    raise FileNotFoundError(ENOENT,
  FileNotFoundError: [Errno 2] No translation file found for domain: 'selinux-python'
