j4n 2e23fadb54 docker: skip redundant cmdeploy run on container restart ...

Replace the old IMAGE_VERSION_FILE/RUNNING_VERSION_FILE mechanism with a
single deploy fingerprint (image_version:sha256(chatmail.ini)) stored at
/etc/chatmail/.deploy-fingerprint. On restart, if the fingerprint matches
the last successful deploy, skip cmdeploy run entirely. The fingerprint
lives on the container's writable layer. On fresh containers, setting
CMDEPLOY_STAGES non-empty in env forces a deploy run regardless of
fingerprint.

Also narrow the /home volume mount to /home/vmail.
