tools perf: Do not check spaces/blank lines when checking header file copy drift
We copy headers from include/, arch/ to allow tools/ use defines, structs from newer kernels and still be able to build on older systems. We then, as part of a build, check if those copies got out of sync, when we emit a warning, so that we can check if something needs to be reflected on the tools, e.g. a 'perf trace' syscall argument beautifier needs tweaking. But we don't have to be super strict with that, for instance, extra spaces, tabs or blank lines aren't problematic, so change check-headers.sh to have "--ignore-blank-lines --ignore-space-change" as default "diff" arguments.
