Do not add routes for localhost to the `dhclient' controlled interface.

Browse Source 
Doing so is bogus if the loop-back interface was not configured.

Typically ``network_interfaces="auto"'' will return the list of
interfaces such that "lo0" is not first.  Thus there are times when
`dhclient' configs an interface before "lo0" is configured.

Under BSD4.4, there's no need to add the above route, as it will be
automatically generated by the kernel.
