* Test that pthread_attr_setinheritsched() sets the inheritance of
* policy and priority.
* Steps:
* 1. Create a pthread_attr struct using pthread_attr_init
* 2. Set the inherit sched in it by calling pthread_attr_setinheritsched
* 3. Change main's priority and policy
* 4. Create a new thread.
* 5. Check that it has correct priority and policy
