go get fails on git clone

[mdavis-xyz]

Steps to reproduce:

On Amazon Linux 2, with no git config set (e.g. git user email), as per the README:

go get github.com/justmao945/mallory/cmd/mallory

Expected result: mallory is downloaded, compiled and installed

Actual result:

# cd /home/ec2-user/go/src/golang.org/x/net; git pull --ff-only

This looks like an error in the git clone step. I'm not familiar with golang, so I don't know how it's cloning the repo. Is the suffix cmd/mallory supposed to be there in the command?
