Bugfix long filenames

Here's what appears to be going on:

1. Wireshark provides dumpcap the original write file via -w,
capture_opts->save_file
2. Because of the ringbuffer options, dumpcap "returns" a new write filename
(save_file + current time) to use and Wireshark saves it to
capture_opts->save_file
3. When Wireshark capture is restarted capture_opts->save_file is used as the
"seed filename" for a new ring.  Repeat Step 2.

So my solution is to save original file name and restore it on a restart. 
Seems a bit kludgy, but it works.

One thing missing from the patch is when to free the orig_save_file memory.  
Because a "restart capture" does a "stop capture", you can't free
orig_save_file then because it needs to persist between captures. It's not a
huge chunk of memory, but its the principle.
