conf: add kvm-host.conf configuration fragmentHEADmaster

Building kvm-image-minimal fails without the 'kvm' DISTRO_FEATURE,
requiring users to manually add it to local.conf. Every other
virtualization platform (Xen, Docker, Podman, k3s, containerd) already
has a composable configuration fragment in conf/distro/include/ that
can be included with a single require line.

Add kvm-host.conf following the same pattern as xen-host.conf: a pure
delta fragment that appends the kvm DISTRO_FEATURE. Composable with
any container profile and the base meta-virt-host.conf.
