yang-maven-plugin: use revision number in packaged yang file name

During controller startup we have a lot of messages like:

2017-01-17 15:47:30,229 | INFO | ime-limited test | YangTextSchemaContextResolver | 165 - org.opendaylight.yangtools.yang-parser-impl - 1.1.0.SNAPSHOT | Provided module name /META-INF/yang/sfc-of-renderer.yang@0000-00-00.yang does not match actual text sfc-of-renderer@2015-11-23.yang, corrected

This boils down to model packaging, where we do not add the revision string to the packaged YANG file name – which a fault of YangToSourcesProcessor, which does have enough information to fill the correct name in.
