    Fix service_mapped_to_host filter for common services

    In Ibecac60d1417269bbe25a280996ca9de6e6d018f, the services in the common
    role were marked as being mapped to the 'all' group, since the
    'service_mapped_to_host' filter expects every service definition to have
    either a 'group' or 'host_in_groups' field. While this allows the filter
    to pass the common services without error, it will not actually show
    them as being mapped to any hosts. This is because the filter uses the
    'group_names' variable, which contains all of the groups that a host
    belongs to, except the default 'all' group.

    This change fixes the issue by returning True from
    service_mapped_to_host when the service's group is 'all'.
