namecache: fix NULL-pointer dereference in namecache-flat
namecache-flat crashes if started on an empty or non-existent file.

This fix at least prevents parsing a 0-byte file, however, looking at
the code it is clear that more needs to be done to prevent crashes in
case of corrupted or incompletely written cache data.
