The benchmarks for dns.lookup() include calling it with an empty
hostname which results in a deprecation warning. This benchmark seems to
be subject to some odd side effects (see Ref below) and we probably
generally don't want to benchmark deprecated things by default anyway.
Remove the deprecated value from the default list. Bonus is that this
will speed up the benchmark.

This patch removes the redundant `require-globals` custom
eslint rule by removing `env: node` in the eslint config
and whitelist the globals that can be accessed in native
modules instead of black listing them. This makes sense
for our `lib/` files because here we are creating the
Node.js environment instead of running in a normal user
land Node.js environment.

So far the benchmarks created a highly specialized function which
would inline exactly to the input. This changes it to provide a
more realistic view to actual input by changing the input on each
iteration. That prevents the function to be to specific.
It also reduces the number of iterations the benchmarks are run to
reduce the overall runtime. A microbenchmark should already show a
significant difference with lower iterations, otherwise the
significance for real world applications is only limited.

Having an experimental feature behind a flag makes change
if we are expecting significant breaking changes to its API.
Since the Worker API has been essentially stable since
its initial introduction, and no noticeable doubt about
possibly not keeping the feature around has been voiced,
removing the flag and thereby reducing the barrier to experimentation,
and consequently receiving feedback on the implementation,
seems like a good idea.
