On some older systems, such as SUSE 11, the compiling error shows
as:
.../dpdk/drivers/net/virtio/virtio_user/virtio_user_dev.c:67:22:
error: ?O_CLOEXEC? undeclared (first use in this function)
The fix is to declare _GNU_SOURCE macro before include fcntl.h.
Fixes: 37a7eb2ae816 ("net/virtio-user: add device emulation layer")
