runtime: enforce minimal node version to 6.9.0

Browse source 
Etherpad 1.6.6 does not run on node <= 5 already.
Node 6.9 is the first LTS release in the 6 series, and comes with npm 3.10.8.

Declarations in package.json are advisory unless the user has set
`engine-strict` config flag.

Updated the docs accordingly.
