Go bash wrapper

• Forwards CLI arguments to /bin/bash
• Adds GO_SH_WRAPPER environment variable

But, why?

Amazon ssm-agent by default runs with sh command and such does does not process user home-directory startup files like ~/.bashrc. This wrapper is stop-gap fix until ssm-agent supports more configuration parameters

Replace standard /bin/sh with sh file produce by running make build on your ec2 instance
