Masahiro Yamada 2047ace966 kbuild: use always-y instead of extra-y 
As commit d0e628cd81 ("kbuild: doc: clarify the difference between
extra-y and always-y") explained, extra-y should be used for listing
the prerequisites of vmlinux.

These targets are not related to vmlinux. always-y is a better fix.
