HID: roccat: fix actual/startup profile sysfs attribute in koneplus

Browse Source 
startup_profile and actual_profile didn't work as expected. Also
as the actual profile is persistent, the distinction between the
two was ambiguous, so both use the same code now and startup_profile
has been deprecated. Also the event is now propagated through
chardev. The userland tool has been updated to support this change.
