ArduCopter 4.4: Param Changes Required for ILX MavCam to work with Survey

CAM1_TYPE: 5
CAM1_TRIGG_DIST: 0

Note: CAM1_TYPE should be set to 5 (MAVLink), because ArduCopter 4.4 does not support MAVLinkCamV2 yet. CAM1_TRIGG_DIST should be 0 because the survey already sets trigg_dist.

Changing CAM1_TYPE requires reboot of flight controller to take effect
