pimd: re-evaluated S,G OILs upon RP changes and for empty SG upstream oils
Topology:
TOR11 (FHR) --- LEAF-11---SPINE1 (RP)MSDP SPINE-2(RP)MSDP --- LEAF-12 -- TOR12 (LHR)

Issue:
In some triggers, S,G upstream is preserved even with the PP timer expiry, resulting
in S,G with NULL OILS. This could be because we create a dummy S,G upstream and
dummy channel_oif for *,G, where RPF is UNKNOWN. As a result, PIM+VXLAN traffic is never
forwarded downstream to LHR.
Fix:
when the S,G stream is running, Determine if a reevaluation of the outgoing interface
list (OIL) is required. S,G upstream should then inherit the OIL from *,G.
Testing:
- Evpn pim tests - TestEvpnPimSingleVtepOneMdt.test_02_broadcast_traffic_spt_zero
- pim-smoke
