tests: ospf point-to-multipoint and suppress

Per the RFC6860, check OSPFv2 using point-to-multipoint
over Ethernet.
Enable the behavior of the RFC6860 using:
  ip ospf prefix-suppress A.B.C.D
See:
  https://www.rfc-editor.org/rfc/rfc6860#section-2.3.2.2

Note that nexthops are not required to assess the checks.
