Run distinct command to dump HIGH connectivity

The dumpsys design in connectivity was updated due to mainline
modularization work. Module can only register with default
priority which is NORMAL. RunDumpSysHigh will not be able to
dump the priority high information in ConnectivityService.
Thus, dump HIGH connectivity specifically to align with legacy
behavior.
