Error when building from source

Bug Description

There is an error when building from source.
Not sure why it happens as PR #382 pinned the bazil.org/fuse version.

Example code (or command)

> go get github.com/GoogleCloudPlatform/cloudsql-proxy/cmd/cloud_sql_proxy
# bazil.org/fuse

Do you know which version of Go you are using? I was able to replicate successfully with GO111MODULE=off go get github.com/GoogleCloudPlatform/cloudsql-proxy/cmd/cloud_sql_proxy, but built successfully with GO111MODULE=on.

We may need to update the README to include explicit instructions for each version...

You are right. It works by adding the GO111MODULE=on.
