mask = rb_to_int(mask);
return RBOOL(int_zero_p(rb_int_and(num, mask)));

Returns true if no bit that is set (=1) in mask is also set in self; returns false otherwise.
Example values:
0b11110000 self
0b00001111 mask
0b00000000 self & mask
true self.nobits?(mask)
0b00000001 self
0b11111111 mask
0b00000001 self & mask
false self.nobits?(mask)
