perf stat: Add header for interval in JSON output
It missed to print a matching header line for intervals.
Before:
# perf stat -a -e cycles,instructions --metric-only -j -I 500
{"unit" : "insn per cycle"}
{"interval" : 0.500544283}{"metric-value" : "1.96"}
^C
After:
# perf stat -a -e cycles,instructions --metric-only -j -I 500
{"unit" : "sec"}{"unit" : "insn per cycle"}
{"interval" : 0.500515681}{"metric-value" : "2.31"}
^C
