runtime: vendor: Bump the netlink package dependency

We need to be able to get the IP family from the netlink route meesages,
and the Route.Family field only got recently added to the netlink
package.

The update generates static check warnings about the call for
nethandler.Delete() being deprecated in favor of a Close() call instead.
So we include the s/Delete()/Close()/ change as part of this PR.
