babel greep and missing characters in TL2019

[Norbert Preining]

Hi Günther,

there is a serious problem in current babel greek.ldf, in that it
defaults to LGR with Unicode engines:

> See https://github.com/latex3/babel/issues/48

because it checks for tuenc being loaded, which is not the case anymore.

Could you please update greek.ldf, because at the moment lots of
documents compiled with xelatex are completely broken with lots of
characters missing.

Thanks.

Norbert
