Add renormalization switch to ketos linegen

Some fonts contain only glyphs for pre-combined Unicode code points,
most notably some of the Greek Font Society's ones, causing Pango to
pick diacritics from other fonts which breaks shaping. Add a
renormalization parameter to the linegen utility enabling normalization
to another form for rendering purposes.
