Proper error check for fwrite in updater.cxx

A less-than-zero check for an unsigned value of type size_t
doesn't make sense, and:

If the return value of fwrite differs from the count parameter,
it means that a writing error prevented the function from completing.
In this case, the error indicator (ferror) will be set for the stream.
