zrepl status: switch back to tview from cview & upgrade to latest (#846)

While investigating https://github.com/zrepl/zrepl/issues/700
I checked in on `zrepl status` dependencies and found that
`cview`, which was/is a fork of tview, appears to be unmaintained.

We switched to it 4.5 years ago in a58ce74.

Checking now, `github.com/rivo/tview` seems to be somewhat maintained
again.
I also checked what k9s uses because that tool came to mind as a Go
terminal UI app.
It does use `tview`, but, a fork that has diverged substantially.

Maybe in another 4.5 years stuff the ecosystem has consolidated...
