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")
