[Automake-NG] [PATCH 21/26] [ng] texi: move some more knowledge from automake to texi-spec.am

[Stefano Lattarini]

* automake.in (handle_texinfo_source): Do not define '$dipfx', nor
use it for the transform '%DEST_INFO_PREFIX%'.
* lib/am/texi-spec.am: Adjust the prefix of the output info file by
adding '$(srcdir)' to it, unless the '?INSRC?' transform is true.
