write_file: use xopen

This simplifies the code a tiny bit, and provides consistent error messages with other users of xopen(). While we're here, let's also switch to using O_WRONLY. We know we're only going to open/write/close the file, so there's no point in asking for O_RDWR. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
