libsrtp: add missing patch

From 8e1dadbcb7ec6be1c568550e97a9e3ce565758bf Mon Sep 17 00:00:00 2001

From: Nirbheek Chauhan <nirbheek@centricular.com>

Subject: [PATCH] Add support for building on/cross-compiling the shared

 library for Windows and OS X

Also ensure that the shared library is versioned, and an implib is created on

Windows.

Commit backported from upstream.
