There was a copy paste error.
Also use the new shim instead of an ifdef to destroy the mouse surface.

3454d4988c GRAPHICS: Disable colorKey when applying a mask to a RGB cursor in SurfaceSdl 
To apply a mask to a RGB (non-paletted) cursor in SurfaceSdl, we use an
intermediary masked_image, where the pixels made transparent by the mask
are replaced by an ARGB color with alpha = 0 (ARGB 0x00000000 in practice).

However the cursor surface still has a key color attached to it by
SDL_SetColorKey (set to 0 currently), which is not sensitive to the alpha
channel, wrongly making opaque black ARGB 0xFF000000 transparent as well.

So we provide an option to disable the key color in such a case.

57893f8d3a SURFACESDL: Refresh cursor scaler along whith standard scaler (bug #14872) 
Otherwise, the cursor scaler and standard scaler may be different types,
which can lead to scaling the cursor with a scaler that normally doesn't
allow it. In this particular bug report, it caused ScummVM to crash.

9f1528e32f SDL: Fix incorrect handling of dirty rect with negative shake offset in SDL1 
Instead of shifting the destination to the left, if was moving the source to
the right, which had the effect of shifting the dirty rect. So part of the
surface that should have been copied to the screen was not, and instead it
was copying part of the surface that did not need to be copied.

dd43a7d2c4 SURFACESDL: Re-add check for _cursorNeedsRedraw 
Partially rolls back a change introduced in
2caa338dbddd9429c766a281231c8fb98701d968; Director relies on the notion
of updateScreen() being near-zero cost if there are no changes.
For example, starting director:henachoco05 went from taking a few
milliseconds to taking 11 seconds, and opening the top menu in
director:easternmind only works on 10% of the screens.

a0cb2fb05e SURFACESDL: Don't pass private flags to SDL_CreateRGBSurface 
sdl_video.h names all of SDL_RLEACCEL, SDL_SRCCOLORKEY and SDL_SRCALPHA
as private and read-only. Documentation mentions them in
SDL_CreateRGBSurface but also says they are automatically set on
either SDL_SetColorKey or on non-zero Amask.

Previously passing them created no problem but miyoo mini SDL gets confused,
so let's never pass the private flags.
