output:fix seg fault in transmitter when weston terminates
Bug-AGL: SPEC-2939 If we stop weston with kill command weston doesn't terminate properly and receives segmentation fault beacause of double free output->link which happened because of wrongly calling weston_output_destroy inside transmitter_destroy function. Also initialize transmitter_output_disable to base disable pointer.
