perf annotate: Print the evsel name in the stdio output 

So that when showing multiple events annotations, we can figure out
which is which:

  # perf record -a -e instructions,cycles sleep 1
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.826 MB perf.data (~36078 samples) ]
  # perf evlist
  instructions
  cycles
  # perf annotate intel_idle 2> /dev/null | head -1
   Percent |	Source code & Disassembly of vmlinux for instructions
  #
