    selftest/eSDK.py: Cleanup when there is an error in setUpClass
    
    Lately autobuilders are experiencing hangs with selftest,
    it seems it is cause if an error happens in setUpClass
    method of oeSDKExtSelfTest class because HTTP server
    keeps running in background.
    
    This patch will ensure tearDownClass will be run if there
    is an error in setUpClass.
