[benchmarks] Add "fuchsia_benchmarks" package as an alias for peridot_benchmarks

After this, I will change infra/config to refer to
"fuchsia_benchmarks" instead of "peridot_benchmarks".  Then I can
remove the original "peridot_benchmarks" package.

Issue: PT-175
Test: run peridot-x64-perf-dawson_canyon bot on this CL via "led" with
  config edited to refer to "fuchsia_benchmarks" instead of
  "peridot_benchmarks"
