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.
