include/ruby/win32.h: explicitly define HAVE_SHUTDOWN

Configuration for mingw32 can't detect 'shutdown' due to wrong -l
option even though it's available (this has been going on for a while,
and it needs to be fixed).
In this situation, include/ruby/missing.h declares a stub shutdown
function since 7ee786388a, and another shutdown decl is came from
system header. They are incompatible at stdcall attribute, so it
causes compilation failure.
This change defines a HAVE_SHUTDOWN to guard a newly introduced stub
decl in include/ruby/missing.h
