Revert "webos-image: nyx-utils=16,v1.1.1"

:Release Notes:
Revert submission 16 of nyx-utils because it generates caches files on
non-volatile partition but it couldn't update the files appropriately
when an image is updated by bootloader. At this moment, it's not easy to
provide proper update solution.

:Detailed Notes:
This reverts commit aa648dc047c7284cfe344f534bee0cea982d18e5, which
reverts this change to nyx-utils:
107bf28 Create json files on non-volatile storage
