The v5.10 kernel no longer guards the task_state_notify_info data
structure with #ifdef CONFIG_SIGEXIT, which causes a
redefinition-related compilation error. Work around this by checking for
the existence of the PR_DO_NOTIFY_TASK_STATE macro, and only define the
PR_DO_NOTIFY_TASK_STATE and the task_state_notify_info structure if the
kernel does not do so.
