build: Do not compress the (already compressed) VM qcow2 images.

The qcow2 format supports compression, and the qcow2 type supported by 'guix
system image' produces compressed qcow2 images.

* Makefile.am (release): Do not re-compress the qcow2 VM images with xz.
* doc/guix.texi (Running Guix in a VM): Adjust VM image URL.
