This looked reasonable at a first glance (the unit test in tests/unit/ needs both), but the condition in meson.build fails if the feature is meant to be detected automatically, and there is also another spot in backends/meson.build where keyutils is used independently from keyring. So let's remove the dependency on keyring again and introduce a proper meson build option instead.
