selftests/bpf: add pyperf scale test Add a snippet of pyperf bpf program used to collect python stack traces as a scale test for the verifier. At 189 loop iterations llvm 9.0 starts ignoring '#pragma unroll' and generates partially unrolled loop instead. Hence use 50, 100, and 180 loop iterations to stress test.
