remote-build spams terminal

[Alan Pope 🍺🐧🐱 🦄]

Using latest snapcraft from latest/stable channel on 22.04.
$ snapcraft version
snapcraft 7.0.7

Trying to use remote-build, and it's outputing the percentage progress on new lines, rather than re-writing the line. I did it in tmux and plain Konsole terminal, and the same effect occurs.
```
$ snapcraft remote-build

Launchpad is messing with the above output. Every line which starts arch=armhf" is a new line. Screenshot shows it better.

Every so often it prints a summary then goes back to spamming the terminal with the progress update again.
