    profiles: Process ghc conf files only once.
    
    A package may be listed in the manifest inputs multiple times.  Avoid
    copying ghc *.conf files twice by deleting duplicates.
    
    * guix/profiles.scm (ghc-package-cache-file)[conf-files]: Delete
      duplicate manifest inputs before copying conf files.
