selftests: mptcp: join: support RM_ADDR for used endpoints or not
Selftests are supposed to run on any kernels, including the old ones not supporting all MPTCP features. At some points, a new feature caused internal behaviour changes we are verifying in the selftests, see the Fixes tag below. It was not a UAPI change but because in these selftests, we check some internal behaviours, it is normal we have to adapt them from time to time after having added some features. It looks like there is no external sign we can use to predict the expected behaviour. Instead of accepting different behaviours and thus not really checking for the expected behaviour, we are looking here for a specific kernel version. That's not ideal but it looks better than removing the test because it cannot support older kernel versions.
