Description
During the migration from go-check to testify we noticed that TestPackfileIterKeepDescriptors was no longer working. This can be related to #1228, or may have happened beforehand.
In either case, that test is currently being skipped. For v6 we could either find a more performant approach to reading the packfile, and remove the KeepDescriptors option, or fix PackfileIter's support for it and unskip this test.
