x86: drop stack-alignment 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 part of commit b33fff07e3e3 ("x86, build: allow
LTO to be selected") and its follow up fix, commit 2398ce80152a ("x86,
lto: Pass -stack-alignment only on LLD < 13.0.0").
