perf top: Teach it to autolocate vmlinux
By relying on logic in dso__load_kernel_sym(), we can automatically load vmlinux. The only thing which needs to be adjusted, is how --sym-annotate option is handled - now we can't rely on vmlinux been loaded until full successful pass of dso__load_vmlinux(), but that's not the case if we'll do sym_filter_entry setup in symbol_filter(). So move this step right after event__process_sample() where we know the whole dso__load_kernel_sym() pass is done. By the way, though conceptually similar `perf top` still can't annotate userspace - see next patches with fixes.
