linux-user: Correct AUXV Cache Line Sizes for PowerPC
Set the AT_ICACHEBSIZE and AT_DCACHEBSIZE entries of the AUXV to match the
CPU model's cache line sizes. This fixes memory clobbering problems on more
recent Book 3s implementations; memset(p, 0, N) will use the dcbz instruction
when N is sufficiently large and many of the newer server CPUs have cache lines
sizes of 128 bytes.
