Remove SSK tests from Signal-iOS xcode test run

Firstly, they aren't compiling (and haven't been for a while), and thus prevent
iOS tests from running and being written. This can and should be fixed.

Secondly, they don't respect the ubsan.supp file. I'm not sure how to fix this.
We may just not be able to run the SSK tests as part of the Signal-iOS test
runner, and instead have to revert to running them from within a separate test
app.
