[Impact]
Commit a25d38b54163 (bpf: relax verifier restriction on BPF_MOV | BPF_ALU) in
Bionic tree
Is causing bpf test compilation failure:

[Fix]
Bionic misses 111e6b45315c (selftests/bpf: make test_verifier run most
programs), which adds the 'retval' member to struct bpf_test. The fix is a
SAUCE patch to remove setting '.retval = 0'.
[Test Case]
Run bpf kernel selftests.
[Regression Potential]
Low. There's a chance that not backporting 111e6b45315c (selftests/bpf: make
test_verifier run most programs) will cause possible bugs on the changes added
by a25d38b54163 (bpf: relax verifier restriction on BPF_MOV | BPF_ALU) to
remain uncaught.
