generating core dumps in winbindd and smbd

[Tim Potter]

I was poking around in the segv signal handling code today as I'm in a
situation where an actual core dump would be handy to have.

The intent of the current code looks like core dumps are to be made in
$LOGDIR/corefiles but the dump_core() function is never executed as the
argument to fault_setup() is never used.

Do we want to keep the existing behaviour or shall I fix it to do what
was intended?
