[PATCH 5/7] test: conftest: set -display none when non-interactive

[Ahmad Fatoum <a.fatoum@barebox.org>]

When running QEMU with --graphic, but in a non graphical session,
running QEMU may fail because it fails to start e.g. the GTK window.

Allow headless tests for these configurations by adding -display none.
