 Fix logic error in GhcMake.enableCodeGenForTH

 transitive_deps_set was incorrect, it was not considering the
 dependencies of dependencies in some cases. I've corrected it and tidied
 it up a little.

 The test case from leftaroundabout, as linked to from the ticket, is
 added with small modifications to flatten directory structure.

 Test Plan: make test TEST=T13949
