Bug description:
  Description:   zkey: Fix listing of keys on file systems reporting DT_UNKNOWN.
  Symptom:       When the zkey key repository is located in a file system that
                 does not have full support for report the file type, such as
                 XFS, the 'zkey list' command does not show any keys, although
                 keys exist in the repository.
  Problem:       The zkey list function uses scandir() to look for files in the
                 zkey key repository directory. It checks the dirent.d_type field
                 to consider only regular files, but skips all others. File
                 systems that do not have full support for returning the file
                 type in d_type will return DT_UNKNOWN instead. zkey skips
                 those directory entries and thus does not show any keys.
  Solution:      Also consider directory entries with d_type = DT_UNKNOWN.
  Reproduction:  Use zkey with a zkey repository directory located in a file
                 system that does not have full support for returning the file
                 type, such as XFS. Generate a key in the repository and then
                 list the key s with 'zkey list'.
                 Note: Newly created XFS file systems usually support returning
                 the file type, but existing XFS file systems might not. To
                 create an XFS file system that does not support returning the
                 file type, use 'mkfs.xfs -f -m crc=0 -n ftype=0' to create
                 the file system.
