LICENSES: add OpenSSL exception

The GPL (both, version 2 and 3) are incompatible with the OpenSSL license.
(OpenSSL has requirements on attribution, which from the GPL's point of
view is a further requirement which is forbidden.)

See https://www.gnu.org/licenses/gpl-faq.html#GPLIncompatibleLibs for
some more details.
