Selftests are supposed to run on any kernels, including the old ones not
supporting all MPTCP features.
One of them is the support of sending an MP_PRIO signal for the initial
subflow, introduced by commit c157bbe776b7 ("mptcp: allow the in kernel
PM to set MPC subflow priority").
It is possible to look for "mptcp_subflow_send_ack" in kallsyms because
it was needed to introduce the mentioned feature. So we can know in
advance if the feature is supported instead of trying and accepting any
results.
