tests: avoid skipif in the system tests for feature detection

@pytest.mark.skipif condition parameter only takes expressions that
evaluates to boolean or string that is eval'd by pytest. This happens
way before the role objects are instantiated and it does not work.

These lambda functions are not executed at all (and can not be
executed because pytest does not support that). The reference to a
function is just evaluated to True therefore the test is always skipped.
