Specify the linux-image-kvm kernel for ubuntu

Browse Source 
This patch switches to using the linux-image-kvm kernel by default.
It produces images that are about 200MB smaller than ubuntu-minimal with
linux-image-generic by using the linux-image-kvm instead of the
linux-image-generic kernel.

The default kernel for the amphora image has switched from
linux-image-generic to linux-image-kvm, resulting in an image size
reduction of about 200MB. The linux-image-kvm kernel works with kvm,
qemu tcg, and Xen hypervisors among others.
