[Patch comes from Jeremy Bicha <jeremy.bicha@canonical.com>'s change done for all other VPN plugins: <https://gitlab.gnome.org/GNOME/NetworkManager-openconnect/-/merge_requests/30>]
Move D-Bus policy file to /usr/share/dbus-1/system.d/ To better support stateless systems with an empty /etc, the old location in /etc/dbus-1/system.d/ should only be used for local admin changes. Package provided D-Bus policy files are supposed to be installed in /usr/share/dbus-1/system.d/.
