picksbr.c: fprintf function pointer with unsigned-long-long cast.

It was previously a double cast, to unsigned long, and then to unsigned
int, and formatted with `0x%x'.  Now we're C99, at least, we can use
unsigned long long and `%#llx'.  Though the fprintf() in question should
be a BUG() that abort(3)s.
