Revert to previous behavior of @dirrmty

1. Show the lstat() warning regardless of DEVELOPER_MODE
2. Cause DEVELOPER_MODE to be fatal here

This retains the extra details when using DEVELOPER_MODE.

Reverts 0054cab61 - Retain lstat() warning in DEVELOPER_MODE but make it
                    non-fatal
Reverts 2ee2f50d4 - Don't emit lstat() warnings/errors with @dirrmtry
