[RFC 6/7] selftests: openvswitch: insert module when running the tests

[Aaron Conole]

The openvswitch tests do not attempt to insert the openvswitch module
automatically.  Now the test will auto load the module and try to
unload it at the end.  The test harness includes the option to not
load the module, which is helpful when developing changes and loading
the module from a different location.
