[depends] bump automake to 1.15.1

[Rechi]

Description

bump automake to version 1.15.1

Motivation and Context

I got the following error on an linux system (debian testing/buster) because of perl 5.26.0.
Unescaped left brace in regex is illegal here in regex; marked by <-- HERE in m/\${ <-- HERE ([^ \t=:+{}]+)}/ at [...]/tools/depends/native/automake-native/x86_64-linux-native/bin/automake line 3936.
automake 1.15.1 has a fix for the regex error.

How Has This Been Tested?

compiled automake on linux and osx
