[PATCH 69/74] perf script: Don't display trace info when invoking scripts

[Arnaldo Carvalho de Melo]

From: Tom Zanussi <tom.zanussi@xxxxxxxxxxxxxxx>

Only display the trace info if using the default event display.  When
invoking scripts we assume they have complete control of what's
displayed so we shouldn't unconditionally display the trace info, and
when generating scripts we don't expect to see trace info obscuring the
output message.
