win32: drop workaround for Wine console buffer

Commit 1ade2225d2 (winansi: allow alternative screen buffer to be
disabled) added a workaround for the broken alternative screen
buffer in the Wine console.

The problem has been fixed in Wine for well over a year:

   https://bugs.winehq.org/show_bug.cgi?id=54287

Remove the workaround.

Saves 80-96 bytes.
