config: Fix name of juno-uboot

The entry for Juno is not actually causing any jobs to be scheduled on the
Juno in my lab since due to a hardware failure that stops EDK2 working it
has fixed u-boot firmware and is registered as 'juno-uboot'. Since KernelCI
matches on this name using 'juno' results in no jobs being scheduled. Fix
that, adjust to say 'juno-uboot'. A 'juno' entry can be re-added if we get
any fully flexible Junos.
