Some build targets of the cuttlefish project don't have the ethernet interface. This CL checks whether the network interface exists before setting it as Thread simulation local interface. Bug: b/378777255 Test: acloudw create --branch git_main --build-id P85047583 --build-target cf_x86_64_auto-trunk_staging-userdebug Change-Id: Ifb1e316f59fac7babf34a7c290d5234853de8653
