tools: Fix make-tarball cli tool usage for development

This tool is used to assist during the creation of ubuntu packages for
release testing. Address the following on the command-line:
 * --help option now print usage
 * Add --orig-tarball which creates named output file
   cloud-init_<release-version>.orig.tar.gz
 * drop unused --verbose option
