[rtmpdump] Patch to recognize __FreeBSD_version

[Marcin Cieslak]

This one is needed:

--- bytes.h	(revision 276)
+++ bytes.h	(working copy)
@@ -25,6 +25,7 @@
  #define __BYTES_H__

  #include <stdint.h>
+#include <sys/param.h>

  #ifdef WIN32
  // Windows is little endian only

otherwise on FreeBSD the endianness check will fallback to the default.
