automation: edit pipeline to prevent running non-selected jobs

Filtering jobs using the selected jobs regex is missing for
qemu-export + yocto jobs when running regular pipelines and eclair jobs
when running scheduled pipelines.

First, set a default value for the selected jobs regex to remove the
need to always check if the variable is empty.

Then add the missing rules to filter out those jobs.
