manuals: use references to the "Build Directory" term

Replace instances of "Build Directory" and "build directory"
(when applicable) by :term:`Build Directory` as already
done in most places.

Doing this, fix the indentation of the paragraphs with
this term.

For subsequent parsing and processing, the name of the Build directory
is available via the :term:`TOPDIR` variable.
