Peteris Rudzusiks 612a8dfb1b vmm: seccomp: Allow all threads to call sched_yield() ...

We occasionally saw cloud-hypervisor crashed due to seccomp violations. The
coredumps showed the HTTP API thread crashing after it attempted to call
sched_yield(). The call came from rust stdlib's mpmc module, which calls
sched_yield() if several attempts to busy-wait for a condition to fulfil fall
short.

Since the system call is harmless and it comes from the stdlib, I opted to allow
all threads to call it.
