Fix installing dependencies

Python package fedora-messaging must be installed for Fedora.

Complicated pip-compile dependency management is replaced with simple
"requirements.txt" which updates pip and required build dependencies.
Poetry is installed using the official way (the version is not pinned;
it is also not included in the final image).
