build-setup: switch zaius to default

The local.conf.sample for Zaius uses 'openbmc-zaius' as its DISTRO,
rather than 'openbmc-openpower'.  This makes a minor change to the
BMC ethernet structure and should probably be used as the default
in our Jenkins builds as well.  Remove the special case for Zaius
and use what is found in the repository's local.conf.sample.
