BookE altivec support brought two new exceptions, but KVM was not updated, so the build broke for all 64-bit booke with KVM enabled. Add the new vectors, but there's more than this required to make Altivec work in the guest, and we can't prevent the guest from turning on Altivec (which can corrupt host state until state save/restore is implemented). Disable e6500 on KVM until this is fixed.
