tests: Handle hostapd dying more gracefully

Browse source 
Catch exceptions from operations that try to remove hostapd interface
and rename the log file. If these operations fail due to socket
connection issues, hostapd has likely died or gotten stuck somewhere.
Report the test case as a failure and stop test run cleanly.
