    tools: ynl: add all headers to makefile deps

    The Makefile.deps lists uAPI headers to make the build work when
    system headers are older than in-tree headers. The problem doesn't
    occur for new headers, because system headers are not there at all.
    But out-of-tree YNL clone on GH also uses this header to identify
    header dependencies, and one day the system headers will exist,
    and will get out of date. So let's add the headers we missed.

    I don't think this is a fix, but FWIW the commits which added
    the missing headers are:

    commit 04e65df ("netlink: spec: add shaper YAML spec")
    commit 4992240 ("ethtool: separate definitions that are gonna be generated")
