[ Upstream commit 76790c7c66ccc8695afc75e73f54c0ca86267ed2 ]

Existing padding test case for btf_dump has a good test that was
supposed to test padding generation at the end of a struct, but its
expected output was specified incorrectly. Fix this.

Fixes: 2d2a3ad872f8 ("selftests/bpf: add btf_dump BTF-to-C conversion tests")
