make METEOR_EDGE optional. Fix node_gyp bug in docker build.

- make METEOR_EDGE optional.
- Fix node_gyp bug in docker build.
- Cannot fix `npm install` because this
runs in the travis container and that is running
on an old ubuntu 12.0 - some way to get a newer version?
- remove npm install for now.
- possibly run tests against docker container
as alternative.
