validation: bluval: Use own repo logparser rules

Instead of creating the logparser rules.txt file on the fly, rely on
the project's git repository providing it.

While at it, add and configure the 'robot' publisher in order to enable
Jenkins dashboard integration and display some nice summaries directly
in the 'blueval' view (using the 'Robot Results + Duration Trend'
column), as well as on the job's overview webpage.
