Comment 2 for bug 2038958

These are the environment variables explicitly allowlisted by lxqt-sudo: https://github.com/lxqt/lxqt-sudo/blob/master/sudo.cpp#L99

I've attached three files; they are the output of env with `qterminal` / `sudo qterminal` / `lxqt-sudo qterminal`.

If we need to allowlist more variables, or skip that filtering entirely, say the word, I'll have an lxqt-sudo upload incoming.

Thanks.
