Improve kernel-install support for initrd files. (#11281)

Browse Source 
The current support in kernel-install for initrd images doesn't copy
over the initrd file or allow a means for it to be specified (it
requires a specific filename in a particular directory).

This patchset adds support for (optionally) providing the name of
initial ramdisk file to copied over and used by kernel-install.
