SELinux: header generation may hit infinite loop
If a permission name is long enough the selinux class definition generation
tool will go into a infinite loop. This is because it's macro max() is
fooled into thinking it is dealing with unsigned numbers. This patch makes
sure the macro always uses signed number so 1 > -1.
