[PATCH] doc: user-manual: ref-manual: remove mentions to BB_SETSCENE_VERIFY_FUNCTION2

["Quentin Schulz" <foss@0leil.net>]

This variable was removed in July 2019 with commit
5deaa5df730a "runqueue: Drop unused BB_SETSCENE_VERIFY_FUNCTION2".

There's no replacement, so let's update the documentation to not mention
this variable anymore.

This was found by running:
git grep -hoP '^   :term:`\K\w+(?=`)' doc/bitbake-user-manual/bitbake-user-manual-ref-variables.rst | \
  xargs -I{} sh -c \
    "grep -Rq --include='*.py' --include='*.conf' --include='*.bbclass' --include='*.bb' --include='*.bbappend' --include='*.inc' \
      -w -E {}'_*(_[a-z]+[0-9a-z]*[a-z]+)*' || \
    echo {}"
