kbuild: rebuild .vmlinux.export.o when its prerequisite is updated
When include/linux/export-internal.h is updated, .vmlinux.export.o
must be rebuilt, but it does not happen because its rule is hidden
behind scripts/link-vmlinux.sh.
Move it out of the shell script, so that Make can see the dependency
between vmlinux and .vmlinux.export.o.
Move the vmlinux rule to scripts/Makefile.vmlinux.
