perf report: Fix --ns time sort key output
If the user specified --ns, the column to print the sort time stamp
wasn't wide enough to actually print the full nanoseconds.
Widen the time key column width when --ns is specified.
Before:
% perf record -a sleep 1
% perf report --sort time,overhead,symbol --stdio --ns
