docs: Makefile: Add dependency to $(YNL_INDEX) for targets other than htmldocs

[ Upstream commit a304fa1d10fcb974c117d391e5b4d34c2baa9a62 ]

Commit f061c9f7d058 ("Documentation: Document each netlink family")
added recipes for YAML -> RST conversion.
Then commit 7da8bdbf8f5d ("docs: Makefile: Fix make cleandocs by
deleting generated .rst files") made sure those converted .rst files
are cleaned by "make cleandocs".

However, they took care of htmldocs build only.

If one of other targets such as latexdocs or epubdocs is built
without building htmldocs, missing .rst files can cause additional
WARNINGs from sphinx-build as follow:

    ./Documentation/userspace-api/netlink/specs.rst:18: WARNING: undefined label: 'specs'
    ./Documentation/userspace-api/netlink/netlink-raw.rst:64: WARNING: unknown document: '../../networking/netlink_spec/rt_link'
    ./Documentation/userspace-api/netlink/netlink-raw.rst:64: WARNING: unknown document: '../../networking/netlink_spec/tc'
    ./Documentation/userspace-api/netlink/index.rst:21: WARNING: undefined label: 'specs'

Add dependency to $(YNL_INDEX) for other targets and allow any targets
to be built cleanly right after "make cleandocs".
