[Tom Yu via RT]

Fix build on systems without RTM_OLD*

For example, FreeBSD has removed RTM_OLDADD and RTM_OLDDEL from its API
in March 2014, with the message:
Garbage collect long time obsoleted (or never used) stuff from routing API

Only attempt to define behavior for these cases if they are defined.
