selftests: mptcp: add helpers to get subflow_info
This patch adds 'get_subflow_info' in 'mptcp_diag', which can check whether
a TCP connection is an MPTCP subflow based on the "INET_ULP_INFO_MPTCP"
with tcp_diag method.
The helper 'print_subflow_info' in 'mptcp_diag' can print the subflow_filed
of an MPTCP subflow for further checking the 'subflow_info' through
inet_diag method.
The example of the whole output should be:
$ ./mptcp_diag -s "127.0.0.1:10000 127.0.0.1:38984"
127.0.0.1:10000 -> 127.0.0.1:38984
It's a mptcp subflow, the subflow info:
