Fix threadapply test
The current test case leaves detached processes running at the end of the test. This patch changes the test to use a barrier wait to ensure all processes exit cleanly at the end of the tests. gdb/testsuite/ChangeLog: 2021-06-02 Carl Love <cel@us.ibm.com> * gdb.threads/threadapply.c: Add global mybarrier. (main): Add pthread_barrier_init. (thread_function): Replace while loop with myp increment and pthread_barrier_wait.
