ref-manual: Updated reference sections for environment setup scripts.

Fixes [YOCTO #5895]

Both section for the environment setup scripts (oe-init-build-env
and oe-init-build-env-memres) were updated to provide some usage
information on the conf-notes.txt file.  This file is where the
default list of images appears that the scripts display upon
completion.
