plug-ins: disable magics detection for Windows CUR and ICO files 

The magics used for detection for CUR and ICO are not very unique and
interfere with the detection of certain types of TGA images.
Since these TGA images are regularly used, it seems better to only base
CUR and ICO detection on the extension, just as we do with TGA version 1
files.
