Subject: [PATCH 2/2] install autoconf-archive-2017.03.21 in CI

The approach is to use the tarball for the 2017.03.21, as it's the
minimal version for dash-version policy of AX_IS_RELEASE macro.

Although we can use APT to install autoconf-archive, but it won't work
for OSX build, and cloning Git takes more time than a simple tarball.
