[trunk] Support for ephemeral boot purpose shouldn't need to use hwe_kernel

[Andres Rodriguez]

https://code.launchpad.net/~quentin-conner/maas/CaringoOS/+merge/299458

When trying to add support for a ephemeral boot method, MAAS always adds the ability to boot a hwe_kernel that, if not available, would cause it to fail because it woudl automatically set it to something i.e. hwe-t, byt default.

MAAS needs to find a way to handle this when bootnig ephemeral to not try to add HWE kernel.
