Rename to kbuild package containing tools to cross-build modules
linux-kbuild-<name>-<arch>-cross. The headers package now depends on
either the native kbuild or a cross variant, unconditionally. This
allows to have unstable source packages between native and cross and is
generally cleaner to describe the cross version.
