fs/ntfs3: Add system.ntfs_attrib_be extended attribute
NTFS-3G provides the system.ntfs_attrib_be extended attribute, which
has the same value as system.ntfs_attrib but represented in big-endian.
Some utilities rely on the existence of this extended attribute.
Improves compatibility with NTFS-3G by adding the system.ntfs_attrib_be
extended attribute.
