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

Browse Source 
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.
