torture: Add a kthread-creation callback to _torture_create_kthread()
This commit adds a kthread-creation callback to the _torture_create_kthread() function, which allows callers of a new torture_create_kthread_cb() macro to specify a function to be invoked after the kthread is created but before it is awakened for the first time.
