Linking error to advapi32 when using BOOST_AUTO_LINK_SYSTEM

Under Windows, the code in random_device.cpp automatically links to the library advapi32.lib.
This uses the auto_link.hpp header combined with the macro BOOST_AUTO_LINK_NOMANGLE to produce the correct library file name to link.

As of version 1.69, it is also possible to use the macro BOOST_AUTO_LINK_SYSTEM, which is exclusive with the NOMANGLE macro.
Using the former causes a link error as the library file name added by auto_link is incorrect.
I would suggest undefining the BOOST_AUTO_LINK_SYSTEM before including the auto_link header in random_device.cpp.
