Revert "all: add a go.mod file"

This reverts commit 5b3e6a55c961c61f4836ae6868c17b070744c590.

Adding a go.mod file has started to cause go get -u golang.org/x/lint
to fail in module mode. This is issue golang/lint#436. Remove the
go.mod file for now in order to resolve the issue. We will re-add
the go.mod file to this repository again when it's a better time
to do so.
