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.

👍 +1 Thanks for hunting down this one :)

I encountered a timeout failure in #4207 but I thought my benchmark was taking too long (which still may be the case).

My understanding is the current timeout is 10 seconds, perhaps raising it to 20 would be sufficient rather than going to 30? What do you think?
