[kirkstone][PATCH] fetch2: npmsw: Add support for the new format of the shrinkwrap file

[belouargamohamed@gmail.com]

From: BELOUARGA Mohamed <m.belouarga@technologyandstrategy.com>

Npm is a package manager that has its own manner to handle installation of packages.
But it is not yocto friendly, for instance NPM fetch dependencies in the middle of compilation.

The shrinkwrap file changed its format over npm versions, but npm does not version
this file, so we can use it properly.
The actual changes make NPM depencies work with the actual shrinkwrap format.
