PPP, move VJ_SUPPORT disabling if LWIP_TCP is not enabled to PPP options
Van Jacobson TCP header compression only apply if TCP is enabled, therefore we need to disable VJ compression if TCP is disabled. We already have conditions to enforce VJ disabling if IPv4 is disabled or if PPPoS is disabled, add TCP to those conditions and remove unecessary VJ_SUPPORT && LWIP_TCP conditions.
