Fix architecture detection on Windows in Makefile, bump SAVEGAMEVER

Browse source 
.. and use YQ2ARCH and YQ2OSTYPE instead of just ARCH and OSTYPE
for the defines, so it's consistent with the engine and xatrix+rogue.

$PROCESSOR_ARCHITECTURE seems to contain the architecture of the host,
but we need the architecture the current MinGW shell is targeting.
$MINGW_CHOST seems to be just that, and on my system it's either
i686-w64-mingw32 (mingw32.exe) or x86_64-w64-mingw32 (mingw64.exe)
(No idea what it looks like for Windows on ARM...)

As fixing this would otherwise break existing savegames, I bumped the
SAVEGAMEVER to "YQ2-4" and added a quirk for older savegameversions:
On Windows i386 savegames that contain "AMD64" instead of "i386" as
architecture are also accepted.
(For YQ2-1 this didn't seem necessary, apparently "i386" was hardcoded)
