ntfs-3g: bump to version 2011.4.12 and enhance

ntfsprogs is now included into ntfs-3g so add an option to
enable/disable it.
It probably doesn't make sense to build ntfsprogs alone so it's not
implemented.

Add the encrypted volume support option now that we've got gnutls.

Also add support for libuuid if it's present.
