selftests: mptcp: join: support local endpoint being tracked 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 is possible to look for "mptcp_pm_subflow_check_next" in kallsyms because it was needed to introduce the mentioned feature. So we can know in advance what the behaviour we are expecting here instead of supporting the two behaviours.
