doc: Remove extraneous spaces from the net-options default value snippet.

Adapting the snippet corresponding to the default value of the net-options
field of the hurd-vm-configuration record shown in the manual would easily
lead to a broken childhurd service, due to the presence of extraneous spaces
in the option string.

* doc/guix.texi (Virtualization Services)[hurd-vm-configuration]
<net-options>: Use string-append to properly form the option string.
