Fix specs

[rocket-turtle]

I think mocka 1.10 is not working with bourne (1.6.0 - November 20, 2014 (15,5 KB))

I tested it on my maschine and it's green for ruby-2.4.10 / ruby-2.5.5 / ruby-2.6.8 / ruby-2.7.6

With ruby-3.0.4 I get these two errors:

..................F........................................F................

Failures:

  1) Terrapin::CommandLine::PosixRunner behaves like a command that does not block does not block if the command outputs a lot of data
     Failure/Error: expect($?.exitstatus).to eq(0)

       expected: 0
            got: 1

       (compared using ==)

     # ./spec/support/nonblocking_examples.rb:6:in `block (2 levels) in <top (required)>'

  2) When an error happens does not blow up if running the command errored before execution

@mike-burns Any chance you can have a quick look at this MR.

I think it gets CI green and other MRs could be testet/ merged.

Maybe test can be moved to GitHub Actions afterwards. https://github.com/thoughtbot/terrapin/pull/16/files
