[maas] AArch64: Preseed Armband repositories

Preseed Armband common repo-comp for Pike, so we get
the updated kernel & other packages from the start.
Requires upstream PR [1].

While at it, also handle related PR merged upstream [2] by
explicitly setting maas.region.subnets name via j2 instead of reclass
param expansion in name (allows us to drop the remaining chunk of the
fabric-from-CIDR patch we used to carry).

Note: opnfv_infra_maas_pxe_network_addres can now be dropped from
pod_config j2 template in Pharos Fuel installer adapter.
