tests: disable toggling clouseau_enabled option in elm tests

Summary:
this option triggers codepaths which require and interface with an
external project not in the EFL tree, so it should not be tested in
the efl tree

also depending on the version of clouseau used, this causes the test
suite to fail 100% of the time

fix T6985
