CLEANUP: chunk: remove misleading chunk_strncat() function

This function claims to perform an strncat()-like operation but it does
not, it always copies the indicated number of bytes, regardless of the
presence of a NUL character (what is currently done by chunk_memcat()).
Let's remove it and explicitly replace it with chunk_memcat().
