Makefile: drop warn-stack-size plugin opt
Now that the minimum supported version of LLVM for building the kernel has
been bumped to 13.0.1, the inner ifeq statement is always false, as the
build will fail during the configuration stage for older LLVM versions.
This effectively reverts commit 24845dcb170e ("Makefile: LTO: have linker
check -Wframe-larger-than") and its follow up fix, commit 0236526d76b8
("Makefile: lto: Pass -warn-stack-size only on LLD < 13.0.0").
