text2pcap: Move SHB and IDB setup to ui/text_import

Move the parameter setup to text_import, so that later it can
be called from the GUI, including the interface name. (This has
to be a separate function because these parameters need to be
set before the call to wtap_dump_open, which is different for
regular files vs temp files vs stdout.)
