feat: add scripts option to lookup table

[richardlau]

If set, "scripts" specifies the scripts from the module's package.json
to run instead of the default "test".

Allows nan to be added (second commit).

CI for this PR running citgm nan: https://ci.nodejs.org/view/Node.js-citgm/job/citgm-smoker-pipeline/68/

Rerun with fixes for Node.js 6 and 8 (avoid use of array.values()):
https://ci.nodejs.org/view/Node.js-citgm/job/citgm-smoker-pipeline/69/console

Almost clean on 6 and 8 (linux-s390x ran on a rebuilt host which appears to be missing curl used to download Node.js).

Building the nan test bindings on Windows is failing for 10 and 11 -- I'm not entirely sure why but they do run on different workers (with VS2017) than the Windows builds for 6 and 8 (VS2015) which passed.

@SimenB Is that also what you need for Jest?

[SimenB]

Yes, perfect!

@richardlau can we go ahead with this?

I released a patch release just before landing this. Currently waiting for Travis CI to complete on the rebased #706 and then I'll land that too and release a new minor that includes this PR.
