gnu: Add go-go-senan-xyz-flagconf

I've fixed the inputs for go-go-senan-xyz-flagconf and cliphist and I've updated the build-system arguments as well as the [synopsis] and [description] fields for cliphist. I believe the formatting issues were caused by my email client--hopefully this time it doesn't mess up the indentation again.

Best, Spencer

* gnu/packages/golang-xyz.scm (go-go-senan-xyz-flagconf): New variable.
