bitbake: fetch2: add the npmsw fetcher

This commit adds a new npmsw fetcher that fetches every npm dependencies
described in a npm shrinkwrap file:

  https://docs.npmjs.com/files/shrinkwrap.json.html

The main package must be fetched separately:

  SRC_URI = "npm://registry.url;package=foobar;version=1.0.0 \
             npmsw://${THISDIR}/npm-shrinkwrap.json"

Since a separation has been created between the package and its
dependencies, the package can also be fetched with a non npm fetcher
without impacting the general behavior:

  SRC_URI = "git://github.com/foo/bar.git;protocol=https \
             npmsw://${THISDIR}/npm-shrinkwrap.json"
