[lit] Add swift-demangle-yamldump as a dependency of the lit test suite.

I added a test to make sure that this utility continued to work as expected...
but I forgot to add the utility as a dependency of the test... *doh*.

Thanks to the buildczar Slava for catching this. All hail the mighty buildczar!
