Add ruby-sslshake pacakge version 1.3.1, required by ruby-inspec-core.
This is a library to simulate SSL and TLS handshake from SSLv2, SSLv3, to
TLS 1.0-1.2.
It does not rely on OpenSSL and is not designed as a replacement either.
It targets full support for even older handshakes, which are not available
in current releases of OpenSSL anymore.
It also aims to be executable on all systems with a sufficiently modern
version of Ruby without any additional requirements or pre-compiled
binaries.
