package/nodejs: add patch to adjust default NodeJS search path

Browse Source 
By default, NodeJS searches global modules in /usr/lib/node, but NPM
installs them in /usr/lib/node_modules/. Therefore by default, if one
installs modules with BR2_PACKAGE_NODEJS_MODULES_ADDITIONAL, they are
not accessible by NodeJS, unless by passing a
NODE_PATH=/usr/lib/node_modules/ variable. Since this is not obvious,
and it's nicer when things work out of the box, we simply patch NodeJS
to look for modules at the right place.

See

for some discussions on this topic.

Subject: [PATCH] lib/internal/modules/cjs/loader.js: adjust default path to
search modules
NPM installs modules in /usr/lib/node_modules/, but by default NodeJS
searches for them only in /usr/lib/node/. We could also set the
NODE_PATH environment variable, but it is more convienient to have
NodeJS configured by default to find modules where they are installed.
