rootdir: fstab: Use the right label for our vendor partition.

  * We renamed 'factory' as 'vendor' on our partition table:

    z2_row:  sgdisk_static --change-name=9:vendor /dev/block/sda
    z2_plus: sgdisk_static --change-name=46:vendor /dev/block/mmcblk0

  Note that partition number for z2_plus may not be the same if you came from Indian's stock
  or from Chinese's stock.

  Check first the output of 'ls -l /dev/block/bootdevice/by-name/factory'

  * Thanks to @cryscript for the idea and his work for z2_plus.
