[timed] Remove "timed" group setup from pre install. Fixes JB#48208

Adding groups in package install phase via oneshot script is subject
to timing problems and can lead to timed service being unable to
change system default timezone.

As adding "timed" group is now handled in sailfish-setup, there is
no need to do it during timed package install.

Also, do not remove "timed" group on timed package uninstall.
