[letterspace] add Xetex compatibility for “letterspace”
When defining a font, Luaotfload interprets the value supplied to the “letterspace” option as a percentage of the font size, mimicking Xetex in yet another respect. In order to preserve the former behavior (no scaling) a new option **kernfactor** is introduced whose value is passed on to the letterspacing feature unmodified.
