perf tools: Parse tracepoints with '-' in system name
Trace events potentially can have a '-' in their trace system name,
e.g. kvm on s390 defines kvm-s390:* tracepoints.
We could not parse them, because there was no rule for this:
$ sudo ./perf top -e "kvm-s390:*"
invalid or unsupported event: 'kvm-s390:*'
This patch adds an extra rule to event_legacy_tracepoint which handles
those cases. Without the patch, perf will not accept such tracepoints in
the -e option.
