[Buildroot] [git commit] package/cjson: add option to build cJSON_Utils

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=bfdcad485d818be674baacf22257ad6280904bbf
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

cJSON_Utils adds support for a few additional JSON RFCs. The size
increase is small (around 12K for ARM32), but it is more than half the
size of cJSON itself. So add a separate config option for cJSON_Utils.
