[Zixing Liu]

libvmod-redis/15.1-1build2 autopkgtest failed on arm64 with:

1650s 1) Command "varnishadm vcl.load test /etc/varnish/test.vcl" stdout is expected to eq "\n"
1650s Failure/Error: its(:stdout) { should eq "\n" }
1650s
1650s expected: "\n"
1650s got: ""
1650s
1650s (compared using ==)
1650s
1650s # ./spec/varnish-redis/use_spec.rb:9:in `block (2 levels) in <top (required)>'

A re-test may be required to see if this is a transient failure.

Later autopkgtest runs on arm64 don't seem to have failed [1]
