fix tests small other changes

Also
 * cloudinit/sources/DataSourceAzure.py: invalid xml in a file called
   'ovfenv.xml' should raise BrokenAzureDatasource rather than
   NonAzureDataSource
 * cloudinit/sources/DataSourceSmartOS.py:
   cloudinit/sources/DataSourceAzure.py
   use 'ephemeral0' as the device name in builtin fs_setup

 * tests/unittests/test_datasource/test_azure.py:
    * always patch 'list_possible_azure_ds_devs' as it calls find_devs_with
      which calls blkid, and dramatically was slowing down tests on my system.
    * test_user_cfg_set_agent_command_plain:
      fix this test to not depend on specific format of yaml.dumps().
    * test_userdata_arrives: add a test that user-data makes it through
