Frontend: Remove redundant call to CompilerInstance::setFileManager, NFC

`ASTUnit::Parse` sets up the `FileManager` earlier in the same function,
ensuring `ASTUnit::getFileManager()` matches `Clang->getFileManager()`.
Remove the later call to `setFileManager(getFileManager())` since it
does nothing.
