When Certbot is run inside a Snap, certain environment variables
are modified. But Certbot sometimes calls out to external programs,
since it uses classic confinement. When we do that, we must modify
the env to remove our modifications so it will use the system's
libraries, since they may be incompatible with the versions of
libraries included in the Snap. For example, apachectl, Nginx, and
anything run from inside a hook should call this function and pass
the results into the ``env`` argument of ``subprocess.Popen``.
