Use sched_yield instead of pthread_yield

pthread_yield is not a standard POSIX function, and is not available
in musl libc. The man page says to "Use the standardized sched_yield(2)
instead"[0].

On glibc, pthread_yield is exactly equivalent to sched_yield[1].

On bionic, pthread_yield is also not available, so on Android, the
tests define a wrapper that just calls sched_yield. This wrapper
is no longer necessary if we just use sched_yield in the first
place.
