[Exim] Small patch for src/transports/appendfile.c, full ver…

Here is the entire patch. Adavantage: Avoids one stat() call on quota
calculation, speeding up the process. Disadavantage: message_size is
not correct, so quota is not 100% correct. Then again, maildir has no
locks, so quota is already not 100% correct.

All in all, things don't get much worse, but they work faster. :)
