test-child-process-send-returns-boolean was unreliable in CI and
locally.

  • use 'SIGKILL' for more reliable process termination
  • replace callback with assert.ifError()
  • increase interval in fixture from 500ms to 9999ms. It's only purpose
    is to keep the process from exiting.

Fixes: #20135

Checklist
  • make -j4 test (UNIX), or vcbuild test (Windows) passes
  • commit message follows commit guidelines

From #20135:

(The timeout also has the unfortunate side effect of leaving a child process running.)

Maybe set the timeout in the child process to a few minutes and have it exit afterwards. By then, it should have either been killed, or we can assume something went wrong with the test.
