ref-manual, dev-manual: Review edits for Build Directory wording.

Did some word-smithing to work around a false statement that
implied externalsrc.bbclass needed to be inherited on a
recipe-by-recipe basis.  This affected the usage section and
the glossary definitions for both EXTERNALSRC and EXTERNALSRC_BUILD.

Also updated the "B" variable description to be more accurate
in the use of the term "Build Directory."
