systemctl: append default suffix only if none present
Simplify unit_name_mangle() and unit_name_mangle_with_suffix() to always behave the same, and only append a suffix if there is no type suffix. If a user says 'isolate blah.device' it is better to return an error that the type cannot be isolated, than to try to isolate blah.device.target.
