[PATCH for-9.1 v3 06/11] vhost-user: enable frontends on any POSIX system |

The vhost-user protocol is not really Linux-specific so let's enable
vhost-user frontends for any POSIX system.
In vhost_net.c we use VHOST_FILE_UNBIND which is defined in a Linux
specific header, let's define it for other systems as well.
