python: Various fixes to the python scripts

Browse Source 
This fixes a few issues uncovered by the recent C module fix.

In lxc-start-ephemeral, the hwaddr code wasn't actually working.
Replace by code that properly iterates through the network interfaces
and sets a new MAC address for each entry.

In the python overlay, catch the newly emitted KeyError when in
set_config_item (or setting any previously unset variable would fail).
