Remove formatting with `linenumber`

[rski]

As pointed out here, formatting the output with linenumber has been deprecated since two years ago and line has been available since v1.0.0.
It might be time to remove linenumber.

I'm down with that. I'm not sure if that's acceptable for 2.1.0, since it was marked deprecated in 1.x, or if we should wait for 3.0.0. Either way, I think we should wait for flycheck to receive its fix, first. @rski please keep us apprised of that effort, and in the meantime we can discuss how quickly we can deprecate it.

[rski]

Ah, the joys of semver .
2.0.0 would've been a good time to remove this, but I only just ran into it. I can leave this open and rebase once 3.0.0 is to be released.

[rnelson0]

Heh, indeed. I do think we will have a 3.x soonish regardless, as p3/Ruby 1.8.7 support disappears, so I will tag this appropriately.

[cdenneen]

@rnelson0 I think there is something still using this. If this was tagged as for 3.x why is it merged in 2.x?
