zkey: Fix listing of keys on file systems reporting DT_UNKNOWN

Browse Source 
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 skip all others.

Unfortunately, not all file systems have full support for returning
the file type in d_type. When the zkey repository is located in a file
system that does not support d_type, such as xfs, zkey list shows no
keys, although the key repository contains keys.

Fix this by also considering directory entries with d_type = DT_UNKNOWN.
