Optimise Dockerfile

[AtomicFS]

The Dockerfile can be optimised:

• prevent apt-get install from installing recommended packages by adding --no-install-recommends
• delete the apt-get lists to reduce container size
  • also consider reducing the Dockerfile to single RUN command to reduce number of snapshots
• use quotes to prevent word splitting
• use WORKDIR to switch to a directory
• possible misspelling: NONOSIVERSION vs NONOSIVERION
