Merge branch 'move SYS() macro to test_progs.h and run mptcp in a dedicated netns'

Browse Source 
Hangbin Liu says:

====================

As Martin suggested, let's move the SYS() macro to test_progs.h since
a lot of programs are using it. After that, let's run mptcp in a dedicated
netns to avoid user config influence.

v3: fix fd redirect typo. Move SYS() macro into the test_progs.h
v2: remove unneed close_cgroup_fd goto label.
====================
