netsniff-ng: Account skipped packets as 'seen' and 'dropped'
The packets filtered out due to pkt_type are incoming packets
effectively dropped and should be accounted as such.
This patch explicitly accounts for the skipped packets number in
skip_packet() and adds this number to the 'drop' and 'seen'
counters in update_rx_stats().
