use strcpy in codes_mapping_get_lp_info

strncpy might prevent bad internal state from destroying everything, but it
also writes MAX_NAME_LENGTH bytes unconditionally, clobbering input if it
isn't long enough. Besides, internal state will only be inconsistent if people
are trying to call codes_mapping_get_lp_info without configuring in the first
place...
