Tweak DiskUsage pie view colors and drawing

Browse Source 
* Use colors from http://haiku-os.org/files/downloads/2007-03-20_haiku-color-palette.png
 * The pie view used a simple multiplication to lighten the colors, leading to overflows. Use tint_color instead
 * The outline of each pie slice was drawn with lines, which did not align perfectly. Use StrokeArc with a slightly bigger pen size than the colored area instead.
