    base-files: always generate default DUID
    
    The previous logic was copied from 12_network-generate-ula, but fails to
    account for upgrades where the "auto" value isn't set (it is set by
    base-files/files/bin/config_generate). Fix this to always set the
    default duid if it isn't set.
    
    Also, rename the file to better reflect what it does.
    
    Closes: #21029
    Fixes: a660a076db5a ("base-files: generate a global DHCP DUID")
