ARM: 6879/1: fix personality test wrt usage of domain handlers
There are optional bits that may complement a personality ID. It is
therefore wrong to simply test against the absolute current->personality
value to determine the effective personality. The PER_LINUX_32BIT is
itself just PER_LINUX with one of those optional bits set.
