[arch-general] Please update to OpenVPN 2.3.8

[Florent M]

Hi everyone,

There are some reasons that openvpn in core is 2.3.6 ?

Please update openvpn package to 2.3.8 asap.

Just update PKGBUILD to 2.3.8, it works, and remove openvpn at .service
because systemd service files are now provided by OpenVPN.

Thanks.

(I'm on good ML ?)
