makepkg: strip debugging symbols into separate folder
When using the "debug" option in combination with "strip", move the
debugging symbols into a separate directory ($pkgdir-debug/usr/lib/debug)
suitable for creating a package from.
Create hardlinks between debugging symbols of hardlinked files and add
symlinks in the .build_id directory if the binary has a build ID.
