Fix to variable names that was missing from the original patch.

For updating the diff, should i upload the proper version of the original patch, or a new patch off of head? I assume the latter.

Indeed. It appears that somehow this patch differs from my local version which does have those 2 places as ${_fibnum}, as well as line 250 should be:
ipv6_static_routes="${ipv6_static_routes} _default_fib${_fibnum}"

Fix truncated line in man page

RTG has stopped working with modern perl without these patches. I've attempted to contact the maintainer for a few weeks but have had no luck. Can we just get the flavour bits of the patch removed and the rest committed? That way we at least get it back to a working state.
