Use public network helper connect_to_fd() instead of open-coding it in
prog_tests/sockmap_ktls.c. This can avoid duplicate code.

This patch looks good.

I would go for the newer connect_to_fd_opts() and stop using the older 
connect_to_fd() in the new code. I just notice there is a newly added "int type" 
argument in the connect_to_fd_opts(). I don't see the "int type" argument is 
useful after removing the connect_to_fd_opts() usage from ip_check_defrag.c. 
This cleanup can be left to a separate patch set. The current patch can stay 
with the older connect_to_fd() for now.
