Subject: [PATCH] Use libbsd for strlcpy if available

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1716361
Upstream Status: iproute2.git commit 508f3c231efb1

commit 508f3c231efb179fb842d222e8151b395937b136
Author: Luca Boccassi <bluca@debian.org>
Date:   Wed Oct 31 18:00:11 2018 +0000

    Use libbsd for strlcpy if available

    If libc does not provide strlcpy check for libbsd with pkg-config to
    avoid relying on inline version.
