linux-initrd: 'expression->initrd' returns the complete file name.
Previously 'expression->initrd' would return the directory that contains the 'initrd' file; now it returns the complete file name for that file. * gnu/system/linux-initrd.scm (expression->initrd)[builder]: Change output file name to "initrd.cpio.gz". Tail-call 'file-append' to return the complete file name. * gnu/system.scm (operating-system-initrd-file): Remove 'file-append' call. * gnu/build/linux-initrd.scm (write-cpio-archive): Check whether OUTPUT already has the ".gz" suffix; rename if before invoking GZIP if it does, and otherwise after. * gnu/system/vm.scm (expression->derivation-in-linux-vm)[builder]: Do not append "/initrd" to #$initrd.
