[gdk-pixbuf] Visual Studio builds: Drop the compatibility math.h

commit 3b405715b93704fe60627b22e4dfdae6a3727158

    Visual Studio builds: Drop the compatibility math.h
    
    This has been superseded by fallback-c89.c, which builds the fallback
    implementation based on the availability of round() and lrintf(), which is
    also pre-set in the pre-configured config.h.win32.in.
