kbuild: generate {spl, tpl}-autoconf.mk only when it is necessary
Before this commit, {spl,tpl}-autoconf.mk was always generated at the top Makefile even if SPL(TPL) build was not selected. This commit moves the build rule of {spl,tpl}-autoconf.mk from the top Makefile to spl/Makefile. It prevents unnecessary {spl,tpl}-autoconf.mk from being generated.
