Rather than download large repositories of files from sources we
don't control and patch files as needed, simply extract the
files from precompiled, known good Purism coreboot images.
This offers multiple advantages:
- single source for all blobs, which we control
- significantly smaller download requirements for end user
- significantly less script complexity
- much, much faster
