Fetching is already implemented by bitbake. Now the question is if we can use 
native npm to install offline.

My understanding was that "npm cache add <tarball>" could be a path, though 
there were at least some issues in the past: 
https://github.com/nodejs/help/issues/944. What only I tried so far was "npm 
cache add <folder>" but that didn't work with npm 6.4.1. Maybe I should also 
check the tarball path. But that would mean unpacking the dependencies into 
${S}/node_modules becomes pointless (well, it already is).
