virtio-loopback: v5: Add recipes for virtio-loopback support

Includes the virtio-loopback kernel module, the adapter
application, the vhost-user devices from QEMU and a Rust
vhost-user-rng device implementation.

v2: Update recipes to conform with the OE-Styleguide
v3: Recipes fixes for generic builds
v4: Generalize the recipes to build for different architectures
v5: Update recipes to comply with the OE-Styleguide
