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")
