util: json: Report non-OOM error on yajl failure

The yajl library returns a wide range of error codes so reporting OOM on
any failure is wrong. In case the error was really based by memory issue
the error reporting will probably cause an abort anyways. Change the
error message so that we know that it happened in JSON at least.
