From: Geliang Tang <tanggeliang@kylinos.cn>

This patch adds a symlink to MPTCP's pm_nl_ctl tool into bpf selftests,
and updates Makefile to compile it.

This is useful to run MPTCP BPF selftests on systems with an old version
of IPRoute2. This tool can be used as an alternative to 'ip mptcp'.

In addition, this tool is used as userspace path manager. "csf" and "dsf"
commands of pm_nl_ctl for creating and destroying subflows, and "ann" and
"rem" commands for signaling ADD_ADDR and RM_ADDR. These commands are not
currently supported in 'ip mptcp' yet.

MAINTAINERS needs to be updated since a new file is added in a non
covered place.
