Previous bpf patch made a change to uapi bpf.h like
@@ -922,7 +922,14 @@ enum bpf_map_type {

where BPF_MAP_TYPE_CGROUP_STORAGE_DEPRECATED and BPF_MAP_TYPE_CGROUP_STORAGE
have the same enum value. This will cause selftest test_libbpf_str/bpf_map_type_str
failing. This patch fixed the issue by avoid the check for
BPF_MAP_TYPE_CGROUP_STORAGE_DEPRECATED in the test.
