modules/meander-2.4GHz.fpd: 2.4 GHz PCB antenna

From ben-wpan, but with two additional parameters:

- orientation: left or right (measurements are only correct for right;
  fped's measurement system doesn't understand mirroring)

- PCB thickness: this determines the size of the "tail" added. We
  assume a zero-sized tail (as in TI's original design) works best
  for a 1.0 mm PCB.
