Jiri Olsa ee4c75887d perf tools: Force period term to overload global settings 
Currently the command line option settings beats the per event period
settings:

With no global settings, we get per-event configuration:

  $ perf record -e 'cpu/instructions,period=20000/' sleep 1
  $ perf evlist -v
  ... { sample_period, sample_freq }: 20000 ...

With 'c' option period setup, we get 'c' option value:
  $ perf record -e 'cpu/instructions,period=20000/' -c 1000 sleep 1
  $ perf evlist -v
  ... { sample_period, sample_freq }: 1000 ...

This patch makes the per-event settings overload the global 'c' option
setup:

  $ perf record -e 'cpu/instructions,period=20000/' -c 1000 sleep 1
  $ perf evlist -v
  ... { sample_period, sample_freq }: 20000 ...

I think the making the per-event settings to overload any other config
makes more sense than current state. However it breaks the current
'period' term handling, which might cause some noise.. so let's see ;-).

Also fixing parse event tests with the new behaviour.
