Add packetdrill coverage for the RFC 9293 reset checks on request
sockets in SYN-RECEIVED.  Verify that an exact RST removes the request,
a non-exact in-window RST sends a challenge ACK without removing it,
and an out-of-window RST is silently discarded.

Also cover an RST|ACK with an unacceptable ACK number to ensure RST
sequence validation runs before ACK-field validation.
