rib: default distance value for new protocols (v2)

Browse Source 
adding protocols and forgetting to update zebra_rib.c currently causes
a beyond end of array access for the default distance value. fix by
making 150 the default distance for unknown routing protocols.

150 is higher than all other IGPs but lower than iBGP (200)
