Selftests are supposed to run on any kernels, including the old ones not
supporting all MPTCP features.

One of them is the support of the MP_FAIL / infinite mapping introduced
by commit 1e39e5a32ad7 ("mptcp: infinite mapping sending") and the
following ones.

It is possible to look for one of the infinite mapping counters to know
in advance if the this feature is available.
