[PATCH openbmc v2 30/34] init: Allow options to be fixed at build time

[OpenBMC Patches]

From: "Milton D. Miller II" <miltonm at us.ibm.com>

If the file /init-options exists copy it to the runtime location
/run/initramfs/init-options.

This allows an initramfs image to be built that will not parse
any u-boot or command line variables by adding a file into the
the image.  This can be done either through a recipe overlay or
additonal package today and could also be a cpio merged into the
initrd in the future.
