pasta: do not leak netlink sock into child
When spawning a child command with pasta command... pasta should not
leak fds that it opened. Only the fds that were already open should be
given to the child.
Run `pasta --config-net -- ls -l /proc/self/fd` from a terminal where
only stdin/out/err are open. The fd 3 was opend by ls to read the
/proc/self/fd dir. But fd 5 is the netlink socket that was opend in
pasta. To prevent such a leak we will open the socket with SOCK_CLOEXEC.
