travis-ci: Build on the xcode11 macOS image.

Fix the macOS builds on the continuous integration
system by requiring a more recently-created system image where
homebrew packages install correctly.

Also switch to declarative syntax for the homebrew package
dependencies, using the built-in Brewfile support instead
of invoking `brew` explicitly.

Travis doesn't update the homebrew three on their default macOS
images, so over time available packages become out-of-date, or
any explicit update step takes longer and longer, slowing the
testing feedback loop.

In this particular instance jobs were failing because homebrew
on the default macOS image wasn't working at all. Without an
update, package installation failed because the `brew bundle`
subcommand had itself bitrotted, while running `brew update`
would time out, taking more than the allowed job time.

Requiring a more recent (non-default) macOS image gets out
tests working again. In the future this will probably need
to be bumped again or restored to the default image.
