initfs: init: add file for base options
Allow an initrd image to include options for init while still allowing additional options to come from the kernel command line and/or u-boot environment variables. This will allow building a netboot image that can specify to run from RAM while allowing the command line to initiate debug or skip copying files from the read-write overlay file system.
