Jorge E. Moreira e40fb21c0d Allow sched_yield in all devices' seccomp policy
The sched_yield system call is somehow called by the code the rust
compiler generates and not directly by the author's implementation. That
along with the fact that it won't get called on every run makes it very
easy to miss when adding a new device (that happened with virtio-snd).
Since that call is quite harmless (it could be argued minijail shouldn't
even block it in the first place) it makes sense to allow it for all
devices.
