openbmc: Generate images with empty NOR sections in the erased state

An erased NOR partition is considered to be a valid JFFS2 filesystem
(i.e. can be successfully mounted as JFFS2). As such there's no need to
execute mkfs to produce an empty JFFS2 image if the target partition is
in the erased state. Thus, when generating the flash-palmetto and
image-rwfs image files, start with a base image file in the erased state
(with all bits set).

The change shifts the common logic to generate the base image files into
a shell function.
