Alexander V. Chernikov 15dbf5a241 netstat: export weight for single-path routes.
* Parse and export newly-added NL_RTA_WEIGHT attribute, providing path
 weight for a non-multipath route. This fixes a number of tests in
 sys/net/routing which rely on this data.
* Remove handling of NL_RTA_KNH_ID in multipath routes, as it is
 not provided.
* Improve kernel/user nexthop index export. As a result,
 for multipath routes:
  * nhg-kidx attribute represents kernel nhg index (always provided)
  * nhg-uidx attribute represents user-provided nhg index (if set)
 for non-multipath routes:
  * nhop-kidx attribute represents kernel nhop index (always provided)
  * nhop-udx attribute represents user-provided nexthop index (if set)
