pimd: increase RPF metric via the peerlink_rif by plus-10
The RPF cost is incremented by 10 if the RPF interface is the peerlink-rif.
This is used to force the MLAG switch with the lowest cost to the RPF
to become the MLAG DF. If a switch has to go via the peerlink-rif to get
to the RP or source it simplly cannot be the designated forwarder.
