The /scripts/removeacct script was failing with "You do not have
permission to remove that account" even when running as root. Switch
to whmapi1 removeacct which uses the WHM API with proper root
authentication context. Also check the whmapi1 result field since
whmapi1 returns exit code 0 even on logical failures.
