PM / hibernate: Use CONFIG_HAVE_SET_MEMORY for include condition
Kbuild reported a build failure when CONFIG_STRICT_KERNEL_RWX was
enabled on powerpc. We don't yet have ARCH_HAS_SET_MEMORY and ppc32
saw a build failure.
I've only done a basic compile test with a config that has
hibernation enabled.
Fixes: 50327ddfbc92 (kernel/power/snapshot.c: use set_memory.h header)
