When running in a container, the root filesystem uses OverlayFS. Due to a quirk of the OverlayFS implementation, nftw() will not include certain files in the walk since their device number differs from the parent directory. We remove the FTW_MOUNT flag to ensure that all child file and directories are deleted before deleting the parent. Bug: 465804122
