sched: Move cpu masks from kernel/sched.c into kernel/cpu.c

kernel/cpu.c seems a more logical place for those maps since they do not really
have much to do with the scheduler these days.

kernel/cpu.c is now built for the UP kernel too, but it does not affect the size
the kernel sections.

$ size vmlinux
