core: don't add prefix route for external addresses
If the user adds an address manually, kernel automatically adds a
prefix route for it unless the address has the NOPREFIXROUTE
flag. When ip_config_merge_and_apply() gets called, NM also adds its
prefix route and so we end up with two routes that differ only for the
metric.
This is a problem because the route added by NM is not removed if the
user removes the previously added address. Also, it seems confusing to
have multiple instances of the same routes.
This commit skips the addition of a prefix route for addresses added
manually outside of NetworkManager.
