x86: vm86 - hide X86_VM_MASK from userland programs

X86_VM_MASK is a kernel specific flag so lets hide it from userland programs

Since and there's already an #ifdef __KERNEL__ section later on in the file, and since X86_VM_MASK isn't used before that, I probably would have been inclined to shift it down there instead of adding a new #ifdef.

But maybe I should just stop heckling... :)

I was thought about that too ;) David, I'll recheck this all today evening (have to go to office now). And please continue heckling - it allows to make this file in particular *better*, so I think it's ok ;)
