[OE-core] [morty][PATCH] image.bbclass: Sorted ctypes to avoid basehash error

[Gerson Fernando Budke]

When selected multiple subimages a similar error could happend:
  Variable do_image_cpio[subimages] value changed \
    from 'cpio.gz.u-boot cpio.gz' to 'cpio.gz cpio.gz.u-boot'
To avoid this, 'ctypes' should be sorted at 'gen_conversion_cmds'.

This garantee that 'CONVERSION_CMD_xxx' are always written in tha same
order and consequently 'do_image_cpio' have the same hash.
