Increase benchmark validation timeout

[marcotc]

I got this flaky test recently:

  1) Tracing benchmarks tracing_trace runs without raising errors
     Failure/Error: raise('Wait time exhausted!')

     RuntimeError:
       Wait time exhausted!
     # ./spec/support/synchronization_helpers.rb:97:in `try_wait_until'
     # ./spec/support/synchronization_helpers.rb:26:in `expect_in_fork'
     # ./spec/datadog/tracing/validate_benchmarks_spec.rb:19:in `block (4 levels) in <top (required)>'
     # ./spec/datadog/tracing/validate_benchmarks_spec.rb:8:in `block (3 levels) in <top (required)>'
     # ./spec/datadog/tracing/validate_benchmarks_spec.rb:7:in `block (2 levels) in <top (required)>'
     # ./spec/spec_helper.rb:237:in `block (2 levels) in <top (required)>'
     # ./spec/spec_helper.rb:122:in `block (2 levels) in <top (required)>'

It looks like this benchmark validation test has a timeout of 10 seconds that was just exceeded in the MacOS CI.

This PR increases it to 30 seconds.
