gluon-radv-filterd: Fix and simplify originators parsing

Previously, only one nexthop was recognized. The parsing of the whole file
failed immediately when two or more hops were possible for *any* originator (not
only for one with a router behind it).

This makes the parser ignore most of the line in the originators table.
