[OE-core] [PATCH 1/2 v2] 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>

Otherwise system will hang since nfs is not disconnected

and remove the judgement of initscript DISTRO_FEATURE when install init
script connman, because inherit systemd will remove init script
