make dependency on polkit to be optional
On gentoo, it is an ebuild in portage to install riseup-vpn with "emerge riseup-vpn". It have 2 runtime dependencies: openvpn and polkit.
onpenvpn have an optional dependency on systemd, which is fine because both systemd and polkit are not installed into my system. Which imply the only blocker is the runtime hard dependency on polkit. Please, make the dependency on polkit to be optional.
