Without this patch, line numbers are missing for first-party code in panic traces. This reverts part of bazelbuild#1563 but keeps the test showing we have a relative path not an absolute one, and adds an integration test showing that line numbers are correctly reported in panic traces. As far as I know, path remapping has been improved in rustc over the last few years, so maybe the behaviour reported in that patch has been fixed.
