selftests/bpf: Add more test case for field flattening
Add three success test cases to test the flattening of array of nested
struct. For these three tests, the number of special fields in map is
BTF_FIELDS_MAX, but the array is defined in structs with different
nested level.
Add one failure test case for the flattening as well. In the test case,
the number of special fields in map is BTF_FIELDS_MAX + 1. It will make
btf_parse_fields() in map_create() return -E2BIG, the creation of map
will succeed, but the load of program will fail because the btf_record
is invalid for the map.
