Justin Cormack 9208496d82 Output kernel command line to a file in the kernel+initrd output case
Trying to find the relevant yaml file was an issue as we now support
`--name` and it might be in a different directory, so although it is
a bit verbose outputing a whole file at least it is more consistent.
