obmc-initfs: look for images in /run/initramfs/image-

Teach update to look for /run/initramfs/image- not /image-*.

When describing how to recover from a corrupted flash by grabbing
the images and running update from the init debug shell, it
became apparent that while at systemd shutdown /run/initramfs/
is mounted at /, it is not the case during init.  Use the
variable image to hold this pathname.
