Subject: [PATCH net] tools: ynl: add header guards for nlctrl

I "extracted" YNL C into a GitHub repo to make it easier
to use in other projects: https://github.com/linux-netdev/ynl-c

GitHub actions use Ubuntu by default, and the kernel headers
there are missing f329a0ebeaba ("genetlink: correct uAPI defines").
Add the direct include workaround for nlctrl.

Fixes: 768e044a5fd4 ("doc/netlink/specs: Add spec for nlctrl netlink family")
Signed-off-by: Jakub Kicinski <kuba@...nel.org>
---
The Fixes tag is a bit unfair here, we never promised very
old headers will work. At the same time Ubuntu may be fairly
popular so seems worth making it work.
