guix system: Reduce size of image produced for 'vm' action.

This reduces the size of the image produced by 'guix system vm' from
26 MiB to 9 MiB.

* gnu/system/vm.scm (system-qemu-image/shared-store):
(system-qemu-image/shared-store-script): Change the default
value of #:disk-image-size to 30 MiB when not FULL-BOOT?.
* guix/scripts/system.scm (system-derivation-for-action): Likewise for
the 'vm' action.
