ext2fs: Update to upstream Hurd-reserved xattr index for "gnu.*".

See
    https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3980bd3b406addb327d858aebd19e229ea340b9a

This supports setting (and reading) of passive trasnlators from
GNU/Linux, e.g.

    dd if=/dev/zero of=file bs=1k count=1000
    losetup /dev/loop0 file
    mke2fs -t ext2 -o hurd -O ext_attr /dev/loop0
    mount -t ext2 -o x-xattr-translator-records /dev/loop0 /mnt
    mkdir -p /mnt/servers/socket
    touch /mnt/servers/socket/1
    setfattr --name=gnu.translator --value='"/hurd/pflocal\0"' /mnt/servers/socket/1
    getfattr --name=gnu.translator /mnt/servers/socket/1
    # file: 1
    gnu.translator="/hurd/pflocal"

* ext2fs/xattr.c (xattr_prefixes): For "gnu.*", use index for
the Hurd (10).
