Revert "Build tests on ubuntu 16.04."

This reverts commit 93c2ca7dfc8feeae374c867c1c679334571a7547.

Building the tests on 16.04 needs a newer boost than it provides;
you can build it statically but then you need to link the boost test
library statically (which requires the removal of BOOST_TEST_DYN_LINK
all over the place).  Doing that fails in libsub for some reason.
