Subject: [PATCH] [irrlicht] Patch moved sysctl.h header file (#13137)

Sysctl has been deprecated for a while and in newer versions of glibc it
is removed which leads to a compilation error on modern Linux. This is
fixed in SVN trunk of irrlich so I copied the include guards from there.
In this case sysctl headers are only loaded for OS X where they are also
actually used.
