Fix stack location for VM86 processes in the !sigaltstack case.
...
I doubt it makes much sense to use the VM's stack for this, but the
old code was doubtless wrong because it potentially overwrote random
user memory.
(It might be a good idea to use the process' pre-vm86()-call stack,
but atm the infrastructure for this is missing.)
