orc install fails to find dependencies when run by the git (for example using git rebase -x)

[Cvelth]

Here's an example:

> git rebase -x 'orc install caliban' COMMIT_SHA
Executing: orc install caliban

Use `--loglevel DEBUG` to diff against all available archives
warning: execution failed: orc install caliban@debug
You can fix the problem, and then run

  git rebase --continue

A known workaround is to unset GIT_DIR and GIT_WORK_TREE variables, for example:

> git rebase -x 'unset GIT_DIR && unset GIT_WORK_TREE && orc install caliban' COMMIT_SHA
