manuals: simplify references to the BitBake User Manual

- Replacing
  :ref:`bitbake:bitbake-user-manual/...`
  by :ref:`bitbake-user-manual/...`

  Adding "bitbake:" as a prefix is not necessary
  as there is no naming conflict between the YP
  and the BitBake manuals (all documents are in
  "bitbake-user-manual/")

- Explaining the rules in the README file

- When necessary, fixing line length in the modified paragraphs.
