drm_hwcomposer: Cuttlefish: Set PRESENT_FENCE_IS_NOT_RELIABLE
Set the capability PRESENT_FENCE_IS_NOT_RELIABLE for Cuttlefish, the virtual Android device.
The virtio gpu module (used on emulators like Cuttlefish) sends frames to the host as fast as possible and does not emulate "real display timing".
