tests: override XDG_RUNTIME_DIR where we use the user runtime dir

We don#t really support systems where XDG_RUNTIME_DIR is not supported for
systemd --user. Hence, let's always set our own XDG_RUNTIME_DIR for tests that
involve systemd --user, so that we know it is set, and that it doesn't polute
the user's actual runtime dir.
