stuck_in_wall tweak

When divine aid granted temporary Passes_walls ability to stuck hero,
it was giving 4d4 turns (4..16, avg 10).  But the first warning that
it's timing out is given at 4 turns left so wouldn't be seen if the
random amount of time picked was the minimum.  Switch to 4d4+4 (8..20,
avg 14) so that the message at 4 turns left will always happen.
