Subject: [PATCH 4.19 09/67] tools/bpf: fix two test_btf unit test cases

4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit 8800cd031af085807028656c6ba7eb7908d78262 ]

There are two unit test cases, which should encode
TYPEDEF type, but instead encode PTR type.
The error is flagged out after enforcing name
checking in the previous patch.

Fixes: c0fa1b6c3efc ("bpf: btf: Add BTF tests")
