[PATCH] ui-patch: Flush stdout after outputting data

[John Keeping]

Since the "html" functions use raw write(2) to STDIO_FILENO, we don't
notice problems with most pages, but raw patches write using printf(3).
This is fine if we're outputting straight to stdout since the buffers
are flushed on exit, but we close the cache output before this, so the
cached output ends up being truncated.

Make sure the buffers are flushed when we finish outputting a patch so
that we avoid this.

No other UIs use printf(3) so we do not need to worry about them.
