use new sdbus++ camelcase

Change I17a8d7479556596a3cf252b3f4eae9c8df547189 will change
how sdbus++ generates names which start with an acronym.
Prepare for this by keying off the SDBUSPP_NEW_CAMELCASE
define to use the new format.

Changes:
    dHCPEnabled -> dhcpEnabled
    dNSEnabled -> dnsEnabled
    iP -> ip
    iPAddress -> ipAddress
    iPv6AcceptRA -> ipv6AcceptRA
    mACAddress -> macAddress
    nICEnabled -> nicEnabled
    nTPEnabled -> ntpEnabled
    nTPServers -> ntpServers
