Documentation: bpf: Fix link to BTF doc

Ross reported broken link to BTF documentation (Documentation/bpf/btf.rst) in Documentation/bpf/bpf_devel_QA.rst. The link in question is written using external link syntax, with the target refers to BTF doc in reST source (btf.rst), which doesn't exist in resulting HTML output.

Fix the link by replacing external link syntax with simply writing out the target doc, which the link will be generated to the correct HTML doc target.

Changes since v1 [1]:

* Reword patch description (I don't see external link semantics on Sphinx documentation [2] when I submit v1).
* Drop the corresponding orphan target definition.
* Rebase on top of current bpf tree.

Ross, do you want to give a Reviewed-by or Acked-by?

Applied, thanks! Looks like kselftest.rst has a similar issue, could you send a fix for this too?
