socat: 1.7.2.4 & 2.0.0-b7.

Socat: Updates to the latest available packages. The developer’s website has been unavailable for me on multiple connections, inside & outside of Homebrew multiple times so I’ve added a mirror to both links.

One of the patches was out of date, having been written into the source code natively and consequently has been removed.

OpenSSL has been a dependency on the various Linux branches for a while now, and given that socat seems to have been built against the newer versions of OpenSSL than Apple ships with OS X I have included that dependency here.

Both socat 1.7.2.2 & 2.0.0-b6 were revealed to contain security flaws, [CVE-2014-0019](http://www.openwall.com/lists/oss-security/2014/01/28/7), and the latest versions included have been patched against those.
