uorb/topics: update delicated match of listener topics

Browse Source 
bug: if user input obr_topic is sensor_gps_sate(wrong topic, which does not exist), the using of `strncmp` will assign idx=8 (as sesnor_gps) in the first.

However, there is no match in the `g_sensor_list`, hence idx=8 will give  out value of `sensor_gps` as output(wrong).

Change: This update aims to match the whole value of sensor name in `g_sensor_list`, while keeping `sensor_name+number` match in this condition.
