Jakub Kicinski 3bfe90527d tools: ynl: protect from old OvS headers
Since commit 7c59c9c8f2 ("tools: ynl: generate code for ovs families")
we need relatively recent OvS headers to get YNL to compile.
Add the direct include workaround to fix compilation on less
up-to-date OSes like CentOS 9.

# Try to include uAPI headers from the kernel uapi/ path.
# Most code under tools/ requires the respective kernel uAPI headers

# All the family headers should be self-contained. We avoid the copying
# by selectively including just the uAPI header of the family directly
# from the kernel sources.
