stapdyn: nullify the pagefault machinations for derefs

We don't need to care about pagefault safety in userspace, but the
definitions making those into preempt_disable led to recursing on
stapdyn_big_dumb_lock (going away in PR14571).  We can just #define
the pagefault_enable/disable away for the dyninst runtime.
