format-patch: use stdout directly

Browse Source 
Earlier, we freopen()ed stdout in order to write patches to files.
That forced us to duplicate stdout (naming it "realstdout") because we
*still* wanted to be able to report the file names.

As we do not abuse stdout that way anymore, we no longer need to
duplicate stdout, either.
