[dpdk-dev] [PATCH] net/virtio-user: fix O_CLOEXEC undeclared error

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")
