Support sqlvet in golangci-lint #15

golangci-lint is a cool metalinter which makes it easy to include lots of popular Go linters in a build process.

There are lots of linters supported already but I didn't see sqlvet.

Once sqlvet uses the go/analysis package we should be able to add it into golangci-lint easily.
