Select specific shortening mode for some fonts

[why]
Most fonts can run with the full naming (--makegroups 1).

But for some (especially with full fledged subfamilies) the names become
too long. Here we need to select more shortening.

[how]
This can be either done/stored in the font-patcher script, but if you
need shortening (and which) still depends on what set of fonts you want
to patch.
So instead we make it a config.cfg option of the unpatched-fonts.
