extras: Add namespace for options in group-virt.example

Commit 23ccabbeb7 introduced a new key "disperse.eager-lock" which
causes a conflict with key "cluster.eager-lock" when option is used
without the qualifying namespace. group-virt.example which gets
installed as /var/lib/glusterd/ groups/virt contains options without
namespace qualifiers. This patch adds the appropriate namespace to all
options in group-virt.example.
