    qemu: don't rely on the non-portable d_type field in dirent
    
    d_type is a non-portable extension to the struct dirent and even if it
    exists, its value may be DT_UNKNOWN if the filesystem doesn't support
    it. This is common with older versions of XFS which have ftype=0
    feature.
