Michael Eischer 3a93e28605 CI: Remove .dockerignore to ensure reproducible builds
Since go 1.18, built binaries also include VCS information such as the
built commit. This information is also included in the official
binaries. To ensure that the Docker container recreates the same
binaries, the .git folder must also be transferred into the container.
Thus, remove the .dockerignore file.

The copied files must also be owned by the current user within the
container, as git refuses to work otherwise.
