Backport v2021 <- v2022: dbus-dos-reply-time: Remove test

Backport !440 (merged)

This test was created to verify some DBUS robustness patches that ended up not being accepted upstream.

The downstream patches have been dropped since v2019 when we rebased to Debian, so this test doesn't have value anymore.

Avoid random failures by removing it.
