sdk-manual: Added link to BB manual fetcher section.

In the "Use devtool upgrade to Create a Version of the Recipe
that Supports a Newer Version of the Software" section, we
reference "fetchers" but do not link to the section on them
in the BB manual.  I added a link.

(From yocto-docs rev: 633ac78daa2ab3bdde17ecb1a203f6addd6ee4af)
