vm: Fix 'vm --full-boot' to produce a sufficient disk image.
* gnu/system/vm.scm (system-qemu-image/shared-store): Add #:disk-image-size and #:full-boot? parameters and honor them. Pass '#:copy-inputs? full-boot?', and change #:inputs argument. * guix/scripts/system.scm (system-derivation-for-action): Pass #:disk-image-size to 'system-qemu-image/shared-store'. * doc/guix.texi (Invoking guix system): Mention use of '--image-size' in conjunction with '--full-boot'.
