weston: Launch DRM backend without input devices

Allow launching Weston 1.11 with DRM backend even
without input devices such as a keyboard, a mouse
or a touchscreen. This fix is convenient for
demonstrations and it is useful for Raspberry Pi
2 and 3 as well as other devices which rely on
DRM backend.
