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

With uprobe_multi link:
