automake: import upstream fix for perl 5.26

Build broke as distributions now include Perl 5.26 and automake
triggered an "Unescaped left brace in regex" error.
Import upstream commit 13f00eb449 to fix that.

Subject: [PATCH] automake: port to Perl 5.22 and later
Without this change, Perl 5.22 complains "Unescaped left brace in
regex is deprecated" and this is planned to become a hard error in
Perl 5.26. See:
http://search.cpan.org/dist/perl-5.22.0/pod/perldelta.pod#A_literal_%22{%22_should_now_be_escaped_in_a_pattern
* bin/automake.in (substitute_ac_subst_variables): Escape left brace.
