Fix VARA-RMS TCP port connection issue (for #17)

 - Bump wine version to 7.1
 - Re-enable wine window manager since VARA graphics glitches are gone in newer versions of wine (tested wine-devel-7.1)
 - Go back to older version of box86 (versions after ed8e01ea cause wine7.1 errors and TCP connection issues with VARA)
 - Maps work again (fixed by either newer wine or different box86)
