Fix a warning from clang about an implicit conversion

xicursorset.c:84:32: warning: implicit conversion changes signedness: 'int' to 'unsigned int' [-Wsign-conversion]
        image = XcursorShapeLoadImage(shape, theme, size);
                ~~~~~~~~~~~~~~~~~~~~~ ^~~~~

The casting is safe because at that point in the code the value is
guaranteed to be non-negative.
