tst-mallocfork2: Fix race condition, use fewer resources
The first SIGUSR1 signal could arrive when sigusr1_sender_pid was still 0. As a result, kill would send SIGSTOP to the entire process group. This would cause the test to hang before printing any output. This commit also adds a sched_yield to the signal source, so that it does not flood the parent process with signals it has never a chance to handle. Even with these changes, tst-mallocfork2 still fails reliably after the fix in commit commit 56290d6e762c1194547e73ff0b948cd79d3a1e03 (Increase fork signal safety for single-threaded processes) is backed out.
