Update build to use yarn from ovirt-engine-nodejs-modules

Now that version 2.0.2 of ovirt-engine-nodejs-modules has yarn
embedded, there is no need to use the ovirt-engine-yarn during
the build process.

  - Removed references to ovirt-engine-yarn in build scripts,
    documentation and error messages

  - Use `make rpm` and `make snapshot-rpm` targets instead of
    patching configure.ac on the fly for snapshot builds

  - make ovirt-web-ui target prints versions for `node` and `yarn` that
    will be used for the build

  - until ovirt-engine-nodejs-modules has an executable for
    yarn, patch in the yarn-*.js from nodejs-modules to do the job
