powerpc/32: implement HAVE_CONTEXT_TRACKING_USER support

Context tracking involves tracking user, kernel, guest switches. 32-bit
shares interrupt and syscall entry and exit code (and context tracking
calls) with 64-bit, and KVM can not be selected if CONTEXT_TRACKING_USER
is enabled, so context tracking can be enabled for 32-bit.
