sequoia-nixbld-user-migration: Try to recreate all missing users instead of just first contiguous set

Browse source 
This script mostly worked for me, but the nixbld6 and nixbld7 accounts for me were still missing. Looking at the script, it seems it's because of the `until` loop in step 2. It assumes only the first contiguous set of users would have disappeared. So 6 and 7 were never restored. This just runs through all 32 users and ensures they exist.
