Fix Dockerfile entrypoints (#467)

Fixes a regression introduced in #224;

entrypoints containing relative paths are incompatible with the usage of
custom working directories.

This causes unexpected failures particularly in CI (GitHub, Gitea,
Forgejo actions), where the repository is often mounted and set as the
working directory - notably, when garnet is used as a `service`.
