[PARISC] fix personality flag check in copy_thread()
Directly comparing task_struct->personality against PER_* is not fully correct, as it doesn't take flags potentially stored in top three bytes into account. Analogically, directly forcefully setting personality to PER_LINUX32 or PER_LINUX discards any flags stored in the top three bytes.
