Do not mount /dev/tty into rootless containers

[mupuf]

Closes: https://bugzilla.redhat.com/show_bug.cgi?id=2165875

Does this PR introduce a user-facing change?

Rootless privileged containers will not mount /dev/tty in the container

This PR should superseed #17301.

@giuseppe: This should address the regression, without needing to revert the commits (which were themselves fixing a regression).

[mupuf]

I would like to write more tests to catch regressions like this one, but I can't do it now. This could however be landed in a separate PR :)

[giuseppe]

could you please add [NO NEW TESTS NEEDED] to the commit? I think it is fine to add this for now without having to add a test (can be added later), so I can backport it
