change user-id of picowizard user to 984

Merged Ghost User requested to merge user-id into master

Currently the picowizard gets userid 1000, since it's the first user created on the system. This makes it so any user that gets created by pico-wizard setup, has user-id 1001.

The first real user on a system should have userid 1000, so make picowizard user have a different userid to enable this.
