FireFly a8c3fbf0cc tests: ignore deprecated uses in rapidcheck
There is a pull request [1] addressing these upstream--it doesn't appear
likely to be merged anytime soon though... this is a no-op til we enable
-Wdeprecated-declarations, but helps in the direction of #744

[1]: https://github.com/emil-e/rapidcheck/pull/325
