Fix 1 zero window advertisement bug and a TCP test flake.
In TestReceiveBufferAutoTuning we now send a keep-alive packet to measure the current window rather than a 1 byte segment as the returned window value in the latter case is reduced due to the 1 byte segment now being held in the receive buffer and can cause the test to flake if the segment overheads were to change. In getSendParams in rcv.go we were advertising a non-zero window even if available window space was zero after we received the previous segment. In such a case newWnd and curWnd will be the same and we end up advertising a tiny but non-zero window and this can cause the next segment to be dropped. PiperOrigin-RevId: 334314070
