[boost] [HEAD][system]error_code.cpp should include <cassert>

Hi, developpers,

In libs/system/src/error_code.cpp, function errno_wmd() calls assert(),
but libs/system/src/error_code.cpp does not include <cassert>,
therefore I encountered compilation error with my code.

The attached patch solved my problem.

Best regards,
