testSetupInstallRoot will be always skipped, because of "wrong" location of 'setup.py':
located twice upper directory related to 'fail2ban/tests/misctestcase.py'

it will used here only, and this distich does not have so great value to save it;
so if you see that comment "below code was actually to print out not missing rather files in 'excess'." you will understand, I mean the code below does not work at all - cycle `for missing in set(got).difference(need)` does nothing, `os.path.exists(missing_full)` returns always false, etc.
