perf trace: Clarify that -e is about syscalls, not perf events in general
This comes from the desire of having -e/--expr to have the same meaning
as for 'strace', while other perf tools use it for --event, which
'trace' honours, i.e. all perf tools have --event in common, but trace
uses -e for strace's --expr.
Clarify it in the --help output.
