selftests/net: packetdrill: add tcp_rcv_wnd_shrink_nomem.pkt

This test verifies
- the sequence number checks using the maximum advertised window
  sequence number and
- the logic for handling received data in tcp_data_queue()

for the cases:

1. The window is reduced to zero because of memory

2. The window grows again but still does not reach the originally
   advertised window
