[Automake-NG] [FYI] [ng] distcheck: --with-included-gettext: with a variable, not a transform

[Stefano Lattarini]

This is mostly a preparatory refactoring in view of future changes.

* automake.in (handle_dist): Define the new internal variable
'am.dist.handle-gettext' to "yes" if the package uses gettext,
to the empty string otherwise.  This takes over the role of the
transform 'GETTEXT', which has thus been removed.
* lib/am/distdir.am (distcheck): Adjust to rely on the new variable
instead than of the removed transform.
