[HarfBuzz] Don't render control characters?

[Olivier Berten]

This might be problematic for the Gregorio project <
http://home.gna.org/gregorio/> which uses fonts where these ranges are
valid (and necessary). It doesn't use OpenType but if HB gets included by
default in lualatex, this could lead to some troubles... (Élie, if you have
some time to check...)
