- removed IDN2_NO_ALABEL_ROUNDTRIP from grovel file for libidn2 (see previous commit message).

This value  has been added lately  to the C library  and some system
  (reportedly:  Debian Buster)  ships an  old version  of the  library
  without this enumeration's value.

  I am commenting out the code, preventing grovel to process it for now.
