Clear the last findings in four ruff groups

Each is the only thing keeping its rule group from being selectable whole.
userutil.py imported ctypes with a star; the names it uses are POINTER,
byref, c_char_p, c_int, c_int32, c_uint and cdll. The oem lookup loop had an
else with no break, so the else always ran. The alert parameter table wrapped
int in a lambda that only forwards to it. And the watchdog interval passed 0
where os.environ.get documents a string, which worked because int(0) is 0.
