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.
