linux-initrd: Return file-like objects instead of monadic values.
This is an incompatible change visible to users via the 'initrd' field of 'operating-system'. However, assuming the user's 'initrd' value tail-calls to 'raw-initrd' or 'base-initrd', the switch to non-monadic style is invisible. * gnu/system/linux-initrd.scm (expression->initrd): Use 'computed-file' instead of 'gexp->derivation'. (raw-initrd, base-initrd): Adjust docstring to mention non-monadic return. * gnu/system/vm.scm (expression->derivation-in-linux-vm): Adjust accordingly. * gnu/system.scm (operating-system-directory-base-entries) (operating-system-initrd-file) (operating-system-boot-parameters): Adjust accordingly. * doc/guix.texi (operating-system Reference) (Initial RAM Disk): Update.
