Group/user mentioned in udev rule prior to creation in postinstall hook

[Kyle Metscher]

Opening as part of a support ticket response.

colord can install udev rules -- in this case, /usr/lib/udev/rules.d/69-cd-sensors.rules -- that mention the group colord before creating it. If "systemctl daemon-reload" is ran between installation of the rules file and creation of the group, it takes 60 seconds longer than usual. This can have a rather noticeable performance impact when installing colord along with many other packages, which occurs frequently in use cases like desktop provisioning.

I imagine it's possible to resolve this by moving the user/group creation from the postinst script to preinst.

Reported in 24.04 with package version 1.4.7-1build2.
