lib/oe/image.py: Add image generation for companion debug filesystem
The companion debug filesystem, enabled with IMAGE_GEN_DEBUGFS, was creating the companion filesystem but was missing the code to actually package it into a usable filesystem. The code (and associated documentation) will allow the debugfs to generate a companion tarball or other image.
