ptp4l: build the interfaces from cmdline after parsing options

this patch causes interfaces to be built after the options have finished
scanning rather than during option parsing. This removes the ability to
specify on the command line separate transport, or dm modes for each port.
Instead this functionality will be added in a follow-on patch via the
configuration file
