Add script to pack npm_binary tarballs with dependencies
Contrary to our experience with bower, not all packages on registry.npmjs.org come with dependencies bundled. This script produces a tarball with bundled dependencies which can be hosted on the Gerrit GCS bucket and used as an npm_binary. Change-Id: I2403c7f0acf759be2508b845d1f359cdf6a65e4e
