linux-initrd: Remove #:to-copy argument of 'expression->initrd'.

Browse Source 
* gnu/system/linux-initrd.scm (expression->initrd): Remove #:to-copy
  parameter.  Remove 'graph-files', and adjust #:references-graphs
  arguments to just list INIT.
  (base-initrd): Remove #:to-copy argument.
* doc/guix.texi (Initial RAM Disk): Adjust accordingly.
