ShaderModule: Fix transform error message 

It was being taken from the pre-transformed program, not the post-transformed program.
If we did get a transform error, the string would be empty.

Also change the signature of RunTransforms() to take a Transform* instead of a Manager*. There's nothing special about Manager anymore - it is just a transform that acts as a group of other transforms.
