Previously, setting this option by default was problematic due to SELinux (as this would also prohibit the transition from PID1's label to the service's label). However, this restriction has since been lifted, hence let's start making use of this universally in our services. On SELinux system this change should be synchronized with a policy update that ensures that NNP-ful transitions from init_t to service labels is permitted. An while we are at it: sort the settings in the unit files this touches. This might increase the size of the change in this case, but hopefully should result in stabler patches later on. Fixes: #1219
