ci: make main meson build uncollapsed + retry failing/flaking jobs

Fixes: #8419 (closed)

• commit:

ci: Retry, retry, retry... No one likes to trigger Marge more than once.
    
    Sadly, have to decrease retry attempts from 2 to 1 for `runner_system_failure` since it's not doable while keeping one attempt for every other failure.
