packetdrill: add test of tcp window clamp socket option

Modifies a test of TCP_WINDOW_CLAMP, including lowering, raising, and lowering again the clamp while the connection is in progress to add a test of brief lowering before raising. Requires a patch to tcp_set_window_clamp discussed as "tcp: enable mid stream window clamp". Signed-off-by: Neil Spring <[email protected]>
