Env vars in nested scripts lost in image gen CLI

[Elise Gafford]

Nesting our scripts within a second bash shell resulted
in an odd libguestfs issue in which environment variables
set within the script were not set. The nested scripting
was never truly necessary for any safety concern (as we
only ever set injected variables before the nested bash
command), and thus is now being removed.
