Kumar Kartikeya Dwivedi b4c574e4b4 libbpf: Use SOCK_CLOEXEC when opening the netlink socket ...

[ Upstream commit 58bfd95b554f1a23d01228672f86bb489bdbf4ba ]

Otherwise, there exists a small window between the opening and closing
of the socket fd where it may leak into processes launched by some other
thread.
