Avoid double appearing of cloned interfaces in the output

Browse Source 
from list_net_interfaces() when network_interfaces=auto.

Rationale: Since the auto case is special, the lesser evil
had to be chosen among not adding cloned interfaces to
_tmplist or removing duplicates from _tmplist after adding
cloned interfaces.  Since list_net_interfaces() must not use
/usr/bin tools, the former "evil" appeared clearer and much
more efficient.  (See the PR audit trail for discussion.)
