Delete and re-create a signal endpoint and ensure that the PM
actually deletes and re-create the subflow.

In the previous tests -- "delete and re-add", we added:

  mptcp_lib_kallsyms_has "subflow_rebuild_header$"

At the beginning of the endpoint_tests() function there is this comment:

  # subflow_rebuild_header is needed to support the implicit flag

Maybe I put the same check on "delete and re-add" by mistake. I don't
think this test depends on the "implicit" type. Or maybe it is, because
its introduction is also linked to some big modifications on the PM
side. In this case, should we have the same check?

  && mptcp_lib_kallsyms_has "subflow_rebuild_header$"

Cheers,
Matt

Uhmm... sounds a little too much defensive programming, but I guess I
can add the test here

Thanks!
