Fix #329: Fails to start with node syntax errors (#330)

* Fix #329: Fails to start with node syntax errors
* s6 v3: Don't try to send commands to the supervision tree, per https://github.com/just-containers/s6-overlay/blob/master/MOVING-TO-V3.md
* Updates to build process to set the correct permissions, as well as through cont-init.d as well as set a fixed (more modern) base image
* Fix build to actually be locked to a specified version of the base image
Update to base image 18.2.0
