perf: Always build the stub perf_arch_fetch_caller_regs version

Now that software events use perf_arch_fetch_caller_regs() too, we
need the stub version to be always built in for archs that don't
implement it.

Fixes the following build error in PARISC:

	kernel/built-in.o: In function `perf_event_task_sched_out':
	(.text.perf_event_task_sched_out+0x54): undefined reference to `perf_arch_fetch_caller_regs'
