[FLINK-7792] [tests][client] Only suppress stdout for CLI tests
## What is the purpose of the change
This PR modifies the CliFrontendTestUtils to only suppress stdout.
Previously we were also suppressing stderr, which also disabled logging.
## Verifying this change
To verify that this does not cause noise tests, run all tests under
`org.apache.flink.client` in `flink-clients` which are the sole users of this
method.
