linux-initrd: Use (guix cpio) instead of GNU cpio.
* gnu/build/linux-initrd.scm (write-cpio-archive): Remove 'open-pipe*' and related calls. Compute list of files in 'files' variable. Use 'cpio:write-cpio-archive'. Remove #:cpio parameter. (build-initrd): Remove #:cpio parameter. * gnu/system/linux-initrd.scm (expression->initrd): Likewise, and adjust BUILDER accordingly. Add (guix cpio) to #:modules.
