    classes/npm: use npm install to do installation
    
    Using "npm install" instead of "cp -a" is the more correct thing to be
    doing here, and ensures that symlinks for executable scripts are put
    into ${prefix}/bin. (I'd prefer ${bindir}, but npm does not allow
    specifying paths at that level - only a prefix.)
    
    Fixes [YOCTO #10460].
