Context

Change the implementation of our node wrapper. The previous implementation was not working for inline tests requiring the node wrapper.

use the binaries field from the env stanza to override the node binary.
use an environment variable to communicate the javascript libraries to preload as we no longer have access to the flags passed to node.
our wrapper needs to be able to execute the real node program but dune will shadow it with our wrapper instead, we save (before shadowing) and restore (inside our wrapper) the PATH environment variable to work around the issue.
