selftests/bpf: Add hashmap test for bpf_for_each_map_elem() helper
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
