sb_efuncs: avoid pointless stdio indirection
We were setting up a FILE* from a file descriptor to pass to sb_fprintf which is a simple macro that calls fileno(fp) to pass the fd down. We can call the fd funcs directly and avoid the whole stdio business. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
