lcitool manifest references "sanity-checks.yml" but doesn't generate the file

In libnbd, I got this pipeline failure:

https://gitlab.com/nbdkit/libnbd/-/pipelines/550544496

lcitool manifest had generated this reference:

https://gitlab.com/nbdkit/libnbd/-/blob/2439fd5c7a07b314ce47728c6fbae16b9a26dcdb/ci/gitlab.yml#L10

but not corresponding file under https://gitlab.com/nbdkit/libnbd/-/tree/master/ci/gitlab
