ntdll: Leave some space around DbgBreakPoint and DbgUserBreakPoint.

CoD: Black Ops 3 and CoD: WWII modify these (and several others) and expect to have enough space for a few instructions. It then verifies later that the patches are still in place, and terminates if the byte sequence do not match. Having small symbols can make the patches to overlap and the check to fail.
