Docker-compose version of nzyme

[r4ulcl]

Docker-compose version of nzyme using host network mode to get access to wlan. Especially made to avoid dependency and installation issues. Uses an ubuntu based docker for Nzyme and a postgres docker for de data.

Thank you! I have made some optimizations to the docker-compose.yml by disabling privileged mode and adding capabilities plus a timezone environment variable for correct logging. Postgres also does not need to run in host network mode, instead the port can be fowarded to only listen on localhost.

Dockerfile - container size optimization

Optimized container size by consolidating layer operations, removing systemd

I'm sorry for the delay. I have modified the code with your suggestions and everything seems to work perfectly. Thank you very much @tadev.
