sdk: include arch/arm/ Linux includes along with arch/arm64/ ones

The Linux headers on arm64 architectures contain references to common arch/arm/ headers which were not bundled by the SDK so far. Check if we're packing the SDK for an arm64 target and if we do, also include arch/arm headers as well. Fixes FS#1725. Signed-off-by: Jo-Philipp Wich <[email protected]>
