[Bernd Kuhls <bernd.kuhls@t-online.de>]

Changelog: https://community.openvpn.net/openvpn/wiki/ChangesInOpenvpn24

While building this defconfig

BR2_PACKAGE_LIBRESSL=y
BR2_PACKAGE_OPENVPN=y

worked with OpenVPN 2.4.4, it is now broken:

Upstream does not provide support for LibreSSL, see
https://openvpn.net/index.php/download/community-downloads.html

"Please note that LibreSSL is not a supported crypto backend."

Added dependency on OpenSSL and license hash.
