linux-user: report ENOTTY for unknown ioctls
The correct error number for unknown ioctls is ENOTTY.
ENOSYS would mean that the ioctl() syscall itself is not implemented,
which is very improbable and unexpected for userspace.
ENOTTY means "Inappropriate ioctl for device". This is what the kernel
returns on unknown ioctls, what qemu is trying to express and what
userspace is prepared to handle.
