selftests/net: Add TCP-AO RST test
Check that both active and passive reset works and correctly sign
segments with TCP-AO or don't send RSTs if not possible to sign.
A listening socket with backlog = 0 gets one connection in accept
queue, another in syn queue. Once the server/listener socket is
forcibly closed, client sockets aren't connected to anything.
In regular situation they would receive RST on any segment, but
with TCP-AO as there's no listener, no AO-key and unknown ISNs,
no RST should be sent.
And "passive" reset, where RST is sent on reply for some segment
(tcp_v{4,6}_send_reset()) - there use TCP_REPAIR to corrupt SEQ numbers,
which later results in TCP-AO signed RST, which will be verified and
client socket will get EPIPE.
No TCPAORequired/TCPAOBad segments are expected during these tests.
Sample of the output:

> ok 2 Verified established tcp connection
> ok 3 sk[0] = 7, connection was reset
> ok 4 sk[1] = 8, connection was reset
> ok 5 sk[2] = 9
> ok 6 MKT counters are good on server
> ok 7 Verified established tcp connection
> ok 8 client connection broken post-seq-adjust
