PR #<!-- -->173311 added a test `clang/test/CodeGen/stack-protector-vars.cpp` that fails if the x86 backend is not built. This adds the proper `REQUIRES` line to fix that.

Should fix the test failure on buildbots that do not build the x86 backend such as https://lab.llvm.org/buildbot/#/builders/190/builds/35171 and https://lab.llvm.org/buildbot/#/builders/154/builds/26976.
