Konstantin Belousov 83ce08538a Use the previous stack entry protection and max protection to correctly
propagate the stack execution permissions when stack is grown down.

First, curproc->p_sysent->sv_stackprot specifies maximum allowed stack
protection for current ABI, so the new stack entry was typically marked
executable always. Second, for non-main stack MAP_STACK mapping,
the PROT_ flags should be used which were specified at the mmap(2) call
time, and not sv_stackprot.
