update go.mod & main.go errors

[kikisdeliveryservice]

Update: So I think this go.mod hadnt been updated since it moved from andrew's repo over here.

so I made a fresh go.mod, fixed some import errors in main.go and fixed a go fmt missing operand.

also renamed the (incorrectly named) ign2to3 to ignconverter

Notably the top level files do specify the package name as ign2to3, is this tested?

Just to clarify:

importing github.com/coreos/ign-converter :

$ make go-deps
go mod tidy
go: finding github.com/coreos/ign-converter latest
go: github.com/coreos/ign-converter@v0.0.0-20200117071129-cfed8ca7a6b4: parsing go.mod: unexpected module path "github.com/coreos/ign2to3"
go: error loading module requirements
make: *** [Makefile:60: go-deps] Error 1

No problem so I import github.com/coreos/ign2to3 :
I get no changes whatsoever to my go.sum (even tho i should!!)

importing `github.com/coreos/ign-converter/ign2to3 : pulls in some stuff/updates my go.sum

I think that this is a relic from when the repo was called ign2to3? if module path was correct as github.com/coreos/ign2to3 then should be able to import using that..

@bgilbert @jlebon sanity check please? go.mod is confusing

[jlebon]

I'm not a golang expert by any means, but yeah it'd be less confusing to just match the package name with the module name and the repo name.

Ok so i redid the go.mod file which hadn't been updated in a long time. I'm unsure what this main.go function is, but it had some problems even running go build ie import issues and golang error, which i also fixed.

Unit tests still pass as well.
