selftests/bpf: Relax TCPOPT_WINDOW validation in test_tcp_custom_syncookie.c.
The custom syncookie test expects TCPOPT_WINDOW to be 7 based on the
kernel’s behaviour at the time, but the upcoming series [0] will bump
it to 10.
Let's relax the test to allow any valid TCPOPT_WINDOW value in the
range 1–14.
