[PATCH bpf-next 2/4] selftests/bpf: Add RUN_MPTCP_TEST macro

["Matthieu Baerts (NGI0)" <matttbe@kernel.org>]

From: Geliang Tang <tanggeliang@kylinos.cn>

Each MPTCP subtest tests test__start_subtest(suffix), then invokes
test_suffix(). It makes sense to add a new macro RUN_MPTCP_TEST to
simpolify the code.
