ref-manual: Added KERNEL_IMAGE_NAME description

The KERNEL_IMAGE_NAME variable is new and is effectively
a renamed KERNEL_IMAGE_BASE_NAME variable now.  I provided a
new glossary description for the new variable.  I updated the
existing KERNEL_IMAGE_BASE_NAME description to note it has
changed.  We can't just delete the old variable as there are
migration notes for previous releases of YP.
