configure.ac: check for linux/rtnetlink.h instead of linux/if_link.h for declarations

Historically, type definitions and declarations related to netlink route
interface attributes were in linux/rtnetlink.h, later they were moved
elsewhere (first linux/if.h, then linux/if_link.h) with the inclusion
of the corresponding header file in linux/rtnetlink.h.

* configure.ac: Use <linux/rtnetlink.h> instead of <linux/if_link.h>
in checks for interface netlink attributes-related declarations
and definitions.
