powerpc/dtrace: Guard fuword64 usage for powerpc64 only
32-bit powerpc doesn't have a fuword64, so only use it on powerpc64. This could also be done elsewhere that splits 32-bit and 64-bit accesses, but adding ifdefs everywhere would just clutter up the source for little benefit. This is the only usage of fuword64 directly; other archs have a dtrace_fuword64_nocheck(), but powerpc does not, and I don't see a need to add it currently. MFC after: 1 week
