[PATCH v4 10/14] docs: conf.py: don't handle yaml files outside Netlink specs

[Mauro Carvalho Chehab <mchehab+huawei@kernel.org>]

The parser_yaml extension already has a logic to prevent
handing all yaml documents. However, if we don't also exclude
the patterns at conf.py, the build time would increase a lot,
and warnings like those would be generated:

    Documentation/netlink/genetlink.yaml: WARNING: o documento não está incluído em nenhum toctree
    Documentation/netlink/genetlink-c.yaml: WARNING: o documento não está incluído em nenhum toctree
    Documentation/netlink/genetlink-legacy.yaml: WARNING: o documento não está incluído em nenhum toctree
    Documentation/netlink/index.rst: WARNING: o documento não está incluído em nenhum toctree
    Documentation/netlink/netlink-raw.yaml: WARNING: o documento não está incluído em nenhum toctree

Add some exclusion rules to prevent that.
