Align EmulateTwoFinger* docs to current behavior.
This corrects man page to mention EmulateTwoFingerMinW and EmulateTwoFingerMinZ are considered together. Old man page read like driver would emulate two-finger even if only pressure OR width (but not both) were supported. Next, add note to align man page with patch that defaults to enabling two-finger emulation on hardware that does not support two-finger detection but does support pressure and width detection.
