automake: just use warnings, with no => FATAL.

Per Perl recommendation:
  https://perldoc.perl.org/warnings#Fatal-Warnings
Suggested by Collin Funk:
  https://lists.gnu.org/archive/html/automake/2025-01/msg00003.html
And in the Perl discussion:
  Perl/perl5#22954 (comment)

* bin/aclocal.in: just use warnings, not making them fatal.
