Until now, the nodejs_abi dependency generator has lived in
nodejs-packaging. However, it depends on (an uses only) /usr/bin/node,
thus only working and being accurate for the default stream.
Moving the generator into a specific stream and modifying it to use
the versioned binary should ensure that it is valid for whatever stream
is used for compiling the binary extension in question.
