wordrec: Fix compiler warning (-Wstringop-truncation) (#1398)

gcc warning: wordrec/language_model.cpp:959:16: warning: ‘char* strncpy(char*, const char*, size_t)’ output truncated before terminating nul copying as many bytes from a string as its length [-Wstringop-truncation] memcpy could also be a little bit faster than strncpy.
