perf tools: Fix misleading add event PMU debug message
Fix incorrect debug message:
Attempting to add event pmu 'intel_pt' with '' that may result in
non-fatal errors
which always appears with perf record -vv and intel_pt e.g.
perf record -vv -e intel_pt//u uname
The message is incorrect because there will never be non-fatal errors.
Suppress the message if the PMU is 'selectable' i.e. meant to be
selected directly as an event.
Fixes: 4ac22b484d4c79e8 ("perf parse-events: Make add PMU verbose output clearer")
