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.
