[PATCH rtems-libbsd v2] ipsec-tools/pfkey: Fix socket leak

[Christian Mauderer]

setkey uses pfkey_open to open a socket. But setkey doesn't close the
socket.

The libipsec functions are used only by user space applications (setkey
and racoon). Adding the wrapper for socket makes sure that the opened
socket is registered and closes if the application exits.

Fixes #4404
