[NTG-context] Generic fontloader and flush_components

[Marcel Fabian Krüger]

Hi,

in font-ots.lua (which becomes part of the generic fontloader)
nuts.flush_components is used, while it seems to be defined for
mkiv and generic in node-gcm.lua, but this file is not included in the
packaged generic fontloader. Therefore the current luatex-fonts-merged.lua
breaks with "trying to call a nil value (upvalue flush_components)".

Could you please add a definition for nuts.flush_components in the
generic version?

Thanks,
Marcel
