[OE-core] [PATCH 6/7] oe-selftest: devtool: fix error message in _test_recipe_contents()

[Paul Eggleton]

If a variable is being set in the recipe when we've explicitly passed
None as the value to _test_recipe_contents() indicating that it
shouldn't be set at all, then we should be printing out the variable
name in the assertion message but it seems like I forgot to do a
substitution. Also include the value for informational purposes.
