[PATCH kvmtool v2 3/6] builtin-run: Do not look for default kernel when firmware is provided

[Julien Thierry <julien.thierry@xxxxxxx>]

When a firmware file is provided, kvmtool is not responsible for loading
a kernel image.

There is no reason for looking for a default kernel image when loading
a firmware.
