[tpp-sched] Make passes which operate on modules operate on modules (#1051)

There was no reason for these passes to only get access to the contained
func.funcs. In case of `-convert-cf-to-llvm` (#1050) it led to the
incorrect behaviour.

This corresponds to what is happening in `DefaultPipeline.cpp`.

Also fixes typo "convert-omp-to-llvm" -> "convert-openmp-to-llvm".
