dwarves: Introduce conf_load->thread_exit() callback
Will be called when a thread exits, initially only in the DWARF loader,
so that pahole can call the btf_encoder associated with the exiting
thread to do the dedup as the last step done in parallel.
Then we'll iterate the btf_encoders list and combine everything into the
first btf_encoder instance that gets then written to disk.
