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.
