Subject: [PATCH 13/16] Catch NetworkNoInterfaces error in docker
 prepare_networks_test

The test "generates a network name and configuration" calls at the end
`process_public_network()`, which can return an empty list if the currently
executing machine has no usable network interfaces (this is typically the case
for workers that build rpm packages in OBS or Koji). This results in an
exception of type Errors::NetworkNoInterfaces to be thrown and causing this test
to fail.

This commit wraps this call in a rescue block to supress this failure.
