fix folder size calculation on FUSE and network file systems

KFileItem::isSlow uses hardcoded logic that returns true if the
filesystem is Smb or Nfs. However,
KFileSystemType::determineFileSystemTypeImpl on Linux returns Nfs also
if the file system in question is a FUSE file system, which includes
NTFS, sshfs, and others.
