[PATCH v2 18/18] gitlab: add a weekly container building job

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

This will hopefully catch containers that break because of upstream
changes as well as keep the container cache fresh.

As we have all the container jobs as dependants we tweaks the
container template to allow scheduled runs. Because we added a new
rules stanza we also need to make sure we catch the normal runs as
well.
