[CI] set longer timeouts for the post-merge continuous job

Since my fix to have a well defined timeout for the build jobs, the build stage of all post-merge continuous pipelines was failing due to timed out tests.

Looking at the successful ones before the change it seems it typically needs around 60-62 minutes (+8-10 relative to pre-merge builds) with around 1650 s for the tests themselves (+400s / 5-6 minutes compared to pre-merge)

Here I try to make use of the new possibility to define the TO per job type
