t: exercise Git/JGit reftable compatibility

Hi,

here's the (hopefully last) version of my patch series that introduces Git/JGit compatibility tests for the reftable format. Only a single commit changed, where I fixed two typos and added a missing signoff.

Thanks!

Patrick

+ will not be able to find the binaries that were set up as root user.

Fix this issue by allowing CI to override the custom path, which allows GitLab to set up a constant value that isn't derived from "$HOME".
