Jiri Olsa 85209e839f selftests/bpf: Add uprobe_multi usdt bench test
Adding test that attaches 50k usdt probes in usdt_multi binary.

After the attach is done we run the binary and make sure we get
proper amount of hits.

With current uprobes:

  # perf stat --null ./test_progs -n 254/6
  #254/6   uprobe_multi_test/bench_usdt:OK
  #254     uprobe_multi_test:OK
  Summary: 1/1 PASSED, 0 SKIPPED, 0 FAILED

   Performance counter stats for './test_progs -n 254/6':

      1353.659680562 seconds time elapsed

With uprobe_multi link:

  # perf stat --null ./test_progs -n 254/6
  #254/6   uprobe_multi_test/bench_usdt:OK
  #254     uprobe_multi_test:OK
  Summary: 1/1 PASSED, 0 SKIPPED, 0 FAILED
