meta-ettus: Add script to automatically set up build environment

Assuming a setup of all the layers as provide by repo and oe-manifests,
this script can be run to initialize a build environment:

    $ source ./meta-ettus/contrib/setup_build_env.sh n3xx v3.13.0.3
    $ bitbake developer-image

In this example, these commands will load an environment, will set the
artifact info to v3.13.0.3, and launch a build of a filesystem for n3xx
type devices.
