====================
selftests: mptcp: misc. small fixes

Here are some various fixes for the MPTCP selftests.

Patch 1 fixes a recently modified test to continue to work as expected
on older kernels. This is a fix for a recent fix that can be backported
up to v5.15.

Patch 2 and 3 include dependences when exporting or installing the
tests. Two fixes for v6.11-rc1.
