Update autobuilder URLs to valkyrie

We have moved to Valkyrie which is hosted on
https://autobuilder.yoctoproject.org/valkyrie. Update the URL in the
documentation.

Also, the YOCTO_AB_URL macro was used in a single location in the
documentation so replace it by the :yocto_ab: custom extlink and remove
the macro.
