He Zhe d9180e23fb perf bench internals inject-build-id: Fix trap divide when collecting just one DSO 
'perf bench internals inject-build-id' suffers from the following error when
only one DSO is collected.

  # perf bench internals inject-build-id -v
    Collected 1 DSOs
  traps: internals-injec[2305] trap divide error
  ip:557566ba6394 sp:7ffd4de97fe0 error:0 in perf[557566b2a000+23d000]
    Build-id injection benchmark
    Iteration #1
  Floating point exception

This patch removes the unnecessary minus one from the divisor which also
corrects the randomization range.
