qemu-log: fix x86 and user logging
5726c27fa913296aafab9f50b912cea5b3709271 broke x86 specific options and user emulation specific stdio buffering. Always enable all log items. They may not be useful for non-x86 targets, but there's no harm either. Fix user emulation buffering by passing around a flag. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
