kbuild: Add support for installing generated asm headers
Generated asm headers are supposed to live in
arch/*/include/generated/asm, but objhdr-y expect them to live in the
same directory they are generated in. Instead of trying to cut that
particular Gordian knot, introduce genhdr-y that takes this into
account; the sole user of objhdr-y, linux/version.h, should be
migrated over at some later date.
