Subject: [PATCH] Add an option for running tests with real modules

To simplify udica testing on Fedora, add an option that allows running
the tests with real system packages (selinux and semanage).

+Subject: [PATCH 1/2] Add an option for running tests with real modules
+
+For testing purposes, the selinux and semanage modules are mocked. This
+allows running the tests without SELinux enabled (e.g. in a container).
+On SELinux-enabled systems, it makes sense to rerun the tests with the
+actual selinux and semanage modules present on the system. For this
+purpose, add a global constant named 'SELINUX_ENABLED'.

+Subject: [PATCH 2/2] Allow running test_main.py directly
+
+By default, the tests are run using the 'python3 -m unittest' command.
+Allow running 'test_main.py' directly so that the 'selinux_enabled'
+argument can be specified.
+
+When running on SELinux-enabled systems, the tests can be rerun with:
+
+    python3 test_main.py selinux_enabled
