perf auxtrace: Add perf_evlist pointer to *info_priv_size()

On some architecture the size of the private header may be dependent on
the number of tracers used in the session.  As such adding a "struct
perf_evlist *" parameter, which should contain all the required
information.

Also adjusting the existing client of the interface to take the new
parameter into account.
