kbuild: move objtool_args back to scripts/Makefile.build
Commit b1a1a1a09b46 ("kbuild: lto: postpone objtool") moved objtool_args to Makefile.lib, so the arguments can be used in Makefile.modfinal as well as Makefile.build. With commit 850ded46c642 ("kbuild: Fix TRIM_UNUSED_KSYMS with LTO_CLANG"), module LTO linking came back to scripts/Makefile.build again. So, there is no more reason to keep objtool_args in a separate file. Get it back to the original place, close to the objtool command. Remove the stale comment too.
