Add waylandsink fallbackguppy_7.0.4guppy_7.0.3guppy_7.0.2guppy_7.0.1guppy/7.0.4guppy/7.0.3guppy/7.0.2guppy/7.0.17.0.47.0.37.0.27.0.1guppy

Add a check for vaapisink availability, and fall back to using
waylandsink if it is unavailable.  This should allow using a non-Intel
board for the cluster demo, though there are potentially issues around
having a H.264 decoder plugin available that may need to be addressed
in the target platform BSP (e.g. Raspberry Pi).
