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.
