perf jevents: Modify match field
The match_field function looks for json values to append to the event
string. As the C code processes these in order the output order matches
that in the json dictionary. Python json readers read the entire
dictionary and lose the ordering. To make the python and C output
comparable make the C code first read the extra fields then append them
to the event in an order not determined by their order in the file.
Modify the pmu-events test so that test expectations match the new
order.
