builtin-run: Warn when ignoring initrd because --firmware was specified
The firmware image is copied into the guest memory with the arch specific
function kvm__load_firmware() in kvm__init(). That function ignores the
initrd file, if the user specified one. Let the user know that the file is
ignored by KVM and the --initrd argument does nothing with --firmware.
