base-files: rename hostname with EUI of mac address
If a label MAC address is provided for device, system
will rename the hostname with OpenWrt_{eui mac address}.
This helps to distinguish between different devices.
Since it's no good idea to nest json_* functions, this code does
not use get_mac_label directly, but only get_mac_label_dt as
external resource.

label MAC address storage, extended commit message]
