[ws-daemon] Remove backup limiter

[csweichel]

Is your feature request related to a problem? Please describe

We're limiting the disk space users can consume using XFS. Prior to that we'd deliberately not create a backup if the workspace size got too large. The latter results in adverse behaviour, because users don't get a backup and no feedback beforehand. Their data is just lost. We should remove this behaviour.

Line 446 in cc2f3b3

opts = append(opts, archive.TarbalMaxSize(int64(s.config.WorkspaceSizeLimit)))

Describe the behaviour you'd like

We should always make backups
