fix: group alternative fingerprint rules (0.1.2)

One Redfish answer (the service root or the error a service refuses it
with) and one landing page (Supermicro/ATEN, iDRAC or iLO) can match,
never all of them. Grouped, the driver's maximum in netOrk's discovery
is 21 instead of 41, and a Supermicro landing page alone (6 of 21)
outranks the "linux" its BMC reports over SNMP (5 of 18).

Requires napalm-device-types 4.8 for FingerprintRule.group.
