Fixed bug 3781 - unbalanced #pragma pack(pop) in close_code.h

Ozkan Sezer

Revision 288 (http://hg.libsdl.org/SDL/rev/2f5a6062db86) excluded the
Watcom compiler from forcing 4 byte structure packing in begin_code.h.
However, it missed updating close_code.h, which now has an unbalanced
#pragma pack(pop) if the compiler is Watcom.  The issue seems to have
crawled into SDL2, too.
