kbuild: fix building vmlinux.o

This was done to let modpost report section mismatch bugs even when the final link failed. Originally I had expected the dependency of $(kallsyms.o) to cover this but it turns out that we need to be even more explicit. Fix this by adding a conditional dependency on firat target used in the kallsyms serie of builds.
