config: restore the possibility of a NULL homehost
As homehost defaults to the system name it is not possible to specify
a NULL homehost.
This patch restored this ability with either --homehost="" or
--homehost="<none>".
This allows the creation of v1.x arrays without a "hostname:"
prefix in the name.
