Another way, works with additional group

As I wrote in comments, it's needed for better compatibility with $wgAddGroup (or you want to make another MakeXXX extensions?). Or it might be not needed by users (if they need just Makesysop).

P.S. I have another implementation based on usergroups.

Okay, I found way to disable it for specified group:

$wgGroupPermissions['group']['makesysop'] = false;
