Backport v2022<-v2023dev3: Disable fstrim service and timer

Backport !15 (merged)

Utility fstrim can cause filesystem issues on some scenarios and there is a list of hardware that does not cope well with it. Since Apertis is a Linux distribution for embedded devices, the default should be not to enable fstrim, as it is in v2021.

Fix the issue by not enabling fstrim service and timer.
