savegame ex.: revamp the way print() works

Basically, instead of re-creating QTextStreams all the time, create it
once, in main(), and then pass it to print() alongside the int
indentation.

Also fix a hard-coded indentation value that should have been relative
to the caller's indentation level.

Pick-to: 6.5 6.2
Task-number: QTBUG-108857
