pipeline(tidb): check more files for cacheing (#4338)

See
https://do.pingcap.net/jenkins/blue/organizations/jenkins/pingcap%2Ftidb%2Fpull_lightning_integration_test/detail/pull_lightning_integration_test/16624/pipeline/

I checked recent three failed run, all of them lacks several files. I
don't know why they are not included in the cache, so this PR extend the
files to check.
