tests: Use variable redirections to dup std{out,err}
Previously, we hardcoded file descriptors 3 and 4 for duplicating stdandard output/error respectively. In preparation for keeping inherited FDs open, switch to using bash's variable redirection feature to dynamically assign FDs. This feature is only available from bash 4.1 onwards, so this marks the end of our support for bash 3. macOS users will need to install a modern bash version to run our tests.
