My earlier patch to just enable --reltime with --time was a little too
optimistic. The --time parsing would accept absolute time, which is
very confusing to the user.
Support relative time in --time parsing too. This only works with recent
perf record that records the first sample time. Otherwise we error out.
Fixes: 3714437d3f ("perf script: Allow --time with --reltime")
