init: Use image of read only file system in RAM if present
If a read-only file system image is in /run, specifically
/run/image-rofs, then mount it instead of the mtd partition.
This will allow running from ram to allow the flash to be updated,
either from a downloaded image, a packaged image, or an image
copied at boot.
