config: copy the return value of prefix_filename
The prefix_filename function returns a pointer to a static
buffer which may be overwritten by subsequent calls. Since
we are going to keep the result around for a while, let's be
sure to duplicate it for safety.
I don't think this can be triggered as a bug in the current
code, but it's a good idea to be defensive, as any resulting
bug would be quite subtle.
