documentation/adt-manual: Adjustments to Yocto Project term

Changes throughout the manual that either eliminate or change
many of the "Yocto Project" strings.  The file structure for
the meta data is now called "source directory."  The build
directory is referred as just that - "build directory."  Any
where the build system is referred to it is called the
"OpenEmbedded build system."
