fix calibre slow startup: bake calibre binaries into image, skip chown on NFS

Browse source 
Custom Docker image pre-installs the universal-calibre mod at build time,
eliminating ~10 min apt-get on every container start. Added NO_CHOWN=true
to skip recursive chown that hangs on NFS mounts. Tightened startup probe
since pod now starts in ~2 min instead of 15-20 min.
