single_entry_point: Retain applied transforms 

This transform does not use the top-level ctx.Clone() method, so we
need to manually copy the applied transforms over to the destination
program.

This fixes the GLSL backend, where this transform was dropping the
applied transforms and breaking a required transform dependency later
in the chain.
