[PATCH mptcp-next v3 6/6] selftests/bpf: Use start_server_str in test_tcp_check_syncookie_user

[Geliang Tang <geliang@xxxxxxxxxx>]

From: Geliang Tang <tanggeliang@xxxxxxxxxx>

Since start_server_str() is added now, it can be used in script
test_tcp_check_syncookie_user.c instead of start_server_addr() to
simplify the code.
