This patch will add the new test, which covers the prctl call PR_SET_NAME command. The test tries to give a name using the PR_SET_NAME call and then confirm it that it changed correctly by using PR_GET_NAME. It also tries to rename it with empty name.In the test PR_GET_NAME is tested by passing null pointer to it and check its behaviour.
