[RFC PATCH] tests/docker: move alpine from edge to tagged release

["Alex Bennée" <alex.bennee@linaro.org>]

Tracking alpine-edge like debian-sid is a moving target. Usually such
rolling releases are marked as "allow_failure: true" in our CI.
However as alpine presents a musl based and provides useful extra
coverage lets track a release branch instead to avoid random
breakages.
