perf annotate: Fix perf data parsing

Browse Source 
perf-annotate doesn't parse perf.data correctly in that it
doesn't read perf header. Fix this by using
mmap_dispatch_perf_file().

Before:

TOTAL events:      17565

      EXIT events:          2
  THROTTLE events:          1
UNTHROTTLE events:          2
      FORK events:         10
      READ events:          1
    SAMPLE events:      14083
