chore: don't compress brokerpaks in integration tests

Compression is computationally expensive, and there's no value in doing it during the integration tests
as the brokerpak will be immediately expanded after being compressed. So we now specify the --compress=false
flag which will mean that the integration tests consume less compute, and might run faster.
