Fix macOS builds in Travis

... which are currently failing with
> Error: The `brew link` step did not complete successfully
> The formula built, but is not symlinked into /usr/local
> Could not symlink Frameworks/Python.framework/Headers
> Target /usr/local/Frameworks/Python.framework/Headers
> is a symlink belonging to python@2. You can unlink it:
>   brew unlink python@2

because the Travis-installed machine apparently has quite a few
Homebrew formulae installed, with an old version of Homebrew,
including a now-removed python@2, and that prevents updates of
python@3.

Remove the obsolete motivation for running (brew update), and replace it
with a similarly-good motivation that the Travis images are just too old
to be relevant to users.
