librt: add test (bug 28213)
This test implements following logic:
1) Create POSIX message queue.
Register a notification with mq_notify (using NULL attributes).
Then immediately unregister the notification with mq_notify.
Helper thread in a vulnerable version of glibc
should cause NULL pointer dereference after these steps.
2) Once again, register the same notification.
Try to send a dummy message.
Test is considered successfulif the dummy message
is successfully received by the callback function.
