[PATCH 2/3] perf intel-pt: Fix displaying PEBS-via-PT with registers

[Adrian Hunter <adrian.hunter@intel.com>]

After recording PEBS-via-PT, perf script will not accept 'iregs' field e.g.

 # perf record -c 10000 -e '{intel_pt/branch=0/,branch-loads/aux-output/ppp}' -I -- ls -l
 ...
 [ perf record: Woken up 1 times to write data ]
 [ perf record: Captured and wrote 0.062 MB perf.data ]
 # ./perf script --itrace=eop -F+iregs
 Samples for 'dummy:u' event do not have IREGS attribute set. Cannot print 'iregs' field.

Fix by using allow_user_set, which is true when recording AUX area data.
