coredns: fix netlink compat for wgsd plugin

wgsd (WireGuard Service Discovery plugin) pulls in
golang.zx2c4.com/wireguard/wgctrl -> mdlayher/genetlink v1.2.0 ->
mdlayher/netlink v1.6.2. This version of netlink calls
mdlayher/socket's Sendmsg/Recvmsg with the old API signatures
(pre-context.Context, single-return-value Sendmsg), but coredns
itself requires mdlayher/socket v0.5.1 which changed these
signatures to include context.Context and return (int, error).

Add a go get step that upgrades netlink to v1.7.2 after the wgsd
plugin dependencies are pulled in, ensuring the build uses a
netlink version compatible with socket v0.5.x.

Should fix:
