`--env` is a podman-specific feature. While it is clear that podman is a
requirement here, switching these to build arguments better expresses
intent.
These values are meant to be configurable at build time, which is
exactly what build arguments are for, while environment variables are
meant to persist in the image built.

Implement a new build pipeline using `podman` and `zig` that is
reproducible and can be run entirely on linux.
We also simplify the versioning system, defaulting to the output of `git
describe` when there are no exact tag matches.
