perf build: Always disable stack protection for BPF skeleton objects
When the clang toolchain has stack protection enabled, the bpf
skeletons build fails with:
error: A call to built-in function '__stack_chk_fail' is not supported.
Since stack-protector makes no sense for the BPF bits, just unconditionally
disable it.
