Yonghong Song 7adfa4ef03 selftests/bpf: Add hashmap test for bpf_for_each_map_elem() helper 
[upstream commit 9de7f0fdab326a37c9f741f0f6c0f1cbc320a5ab]

A test case is added for hashmap and percpu hashmap. The test
also exercises nested bpf_for_each_map_elem() calls like
    bpf_prog:
      bpf_for_each_map_elem(func1)
    func1:
      bpf_for_each_map_elem(func2)
    func2:

  $ ./test_progs -n 45
  #45/1 hash_map:OK
  #45 for_each:OK
  Summary: 1/1 PASSED, 0 SKIPPED, 0 FAILED
