change applies the same strictness when connecting to Rails over TCP.

Added GL_PROTOCOL as an ENV variable to gitCommand

With this MR we are now populating an ENV variable called `GL_PROTOCOL` when calling the `gitCommand` method. This will allow GitLab to allow or deny the request based on the allowed Git access protocols defined in the Application Settings.

This MR is needed for:

gitlab-org/gitlab-shell!62
