[OE-core] [PATCH] connman: ignore the networking device which nfs for rootfs is working on

[rongqing.li at windriver.com]

From: Roy Li <rongqing.li at windriver.com>

Create connmand-nfs.service, which will run a script to ignore the
networking device when root is nfs.
Connmand-nfs.service will be run only when root is not nfs
