Fix services tty output

[Itxaka]

• interactive installer: output was not connected to tty so it was impossible to answer any questions
• reset: was not getting the output and taking over the tty so it got overwritten by other output. It could be stopped in the middle
• installer: same as above but it could lead to stopping the install in the middle of it
• recovery: same as above, QR code didnt even display

journal+console should still print to tty1 as long as tty1 is the default system console. In other words, the only way journal+console should be different from tty is that is should also log to journalctl. The reason I changed it in the first place was that in tests there was not way to get the installer's output since we couldn't read the tty1 (that's the only shown in the graphical window) and there was nothing logged to journalctl either.

If there something doesn't work, we should at least understand why it doesn't work before changing it back.

I don't get why it doesn't work, probably systemd is mangling the output somehow but it doesn't work as expected. You can try yourself by testing master with interactive install or recovery and see how it breaks the tty1 output. With this, which was the original setting from a long time ago, it doesn't.

But to make it work and not keep it broken we need to reverse this to a working state and then change it back to jornal+console as currently is a regression.

I wonder if the way we interact by Kairos agent is the reason, maybe we need to do changes there.

[jimmykarily]

I'm fine to revert it for now to fix the regression. Let's open a new issue to investigate further and bring the change back properly.

umm, for the interactive installer at least, this is necessary to set the tty otherwise we got no control over the input/output with our current implementation.

maybe we could workaround the others somehow?
