Upcoming changes will create architecture-specific asm/auxvec.h headers. Add asm-generic infrastructure to handle the fallbacks for architectures which are not migrated yet and those which won't require their own definition. Extend the list of includes in linux/auxvec.h to cover all potential low-level auxvec.h headers.
