[bpf-next,2/6] selftests/bpf: Make start_mptcp_server static

Commit Message

From: Geliang Tang <[e-mail]>

start_mptcp_server() shouldn't be a public helper, it only be used in
MPTCP tests. This patch moves it into prog_tests/mptcp.c, and implenments
it using make_sockaddr() and start_server_addr() instead of using
start_server_proto().
