superproject: Log syncstate's parameter as data-json it it is an array.

All the values of syncstate are strings, check the first byte and last
byte to see if it is an array. For syncstate data, there were no false
positives.

Tested:
$ repo_dev sync

Verified event logged for argv is "data-json".

$./run_tests
