selftests/bpf: Fix bpftool synctypes checking failure

kernel-patches/bpf failed with error:
  Running bpftool checks...
  Comparing /data/users/ast/net-next/tools/include/uapi/linux/bpf.h (bpf_map_type) and
            /data/users/ast/net-next/tools/bpf/bpftool/map.c (do_help() TYPE):
            {'cgroup_storage_deprecated', 'cgroup_storage'}
  Comparing /data/users/ast/net-next/tools/include/uapi/linux/bpf.h (bpf_map_type) and
            /data/users/ast/net-next/tools/bpf/bpftool/Documentation/bpftool-map.rst (TYPE):
            {'cgroup_storage_deprecated', 'cgroup_storage'}
The selftests/bpf/test_bpftool_synctypes.py runs checking in the above.

The failure is introduced by Commit c4bcfb38a95e("bpf: Implement cgroup storage available
to non-cgroup-attached bpf progs"). The commit introduced BPF_MAP_TYPE_CGROUP_STORAGE_DEPRECATED
which has the same enum value as BPF_MAP_TYPE_CGROUP_STORAGE.

In test_bpftool_synctypes.py, one test is to compare uapi bpf.h map types and
bpftool supported maps. The tool picks 'cgroup_storage_deprecated' from bpf.h
while bpftool supported map is displayed as 'cgroup_storage'. The test failure
can be fixed by explicitly replacing 'cgroup_storage_deprecated' with 'cgroup_storage'
in uapi bpf.h map types.
