3efdb5c94b Reject reserved system usernames in the configurator
The username regex accepted names that already exist on the target, so
useradd failed inside arch_install_system — after the disk had been
partitioned and formatted, which is the worst point to discover it.

From #59 by @wolfgangw, applied to quattro; it was opened against main.
