sphinx: add links for Yocto project website

In DocBook, variables are used to create custom links (note that it is
not consistent everywhere, since some web addresses are still
hardcoded), such as YOCTO_HOME_URL, YOCTO_GIT_URL, YOCTO_WIKI_URL,
YOCTO_BUGS_URL and YOCTO_DL_URL..

In Sphinx they are replaced with extlinks.

 the left a grouping of Git repositories titled "Yocto Linux Kernel".
 Within this group, you will find several Linux Yocto kernels developed
 and included with Yocto Project releases:
