Implement some missing syscalls and "fix" one, which fixes a Project Diva 2nd hang, and possibly other games that rely on sceUtilityScreenshotGetStatus to return success, since they tend to wait forever for the dialog to finish. I'd like to implement the dialog and functionality someday, but for now, this works fine.
Also implement stub for sceRtcSetAlarmTick, though Diva 2nd doesn't care if it's implemented or not.
Fix logging; forgot to remove those. :P
Fix more logging.
