    ci: Set default verbosity to 1 and allow changing it
    
    The logs will contain more messages by default, which should help
    with debugging test failures in CI.
    
    You can also control these variables if you start a pipeline from
    https://gitlab.gnome.org/GNOME/tracker/pipelines/new, for example you
    could rerun the test suite with TRACKER_VERBOSITY=3 to see many
    more messages. (We don't do this by default as each log file would
    be enourmous).
