Prevent overflow for block number in buffile.c

As coded, the start block calculated by BufFileAppend() would overflow
once more than 16k files are used with a default block size.  This issue
existed before b1e5c9fa9ac4, but there's no reason not to be clean about
it.

Per report from Coverity, with a fix suggested by Tom Lane.
