properly handle nfsroot w.r.t. network config

Description

If booting with the root filesystem on NFS, the switchports and network interfaces must not be reset (reads: must NEVER be reset; not before, during or after failsafe message; not on boot time; not with ifup -a or ifdown -a; not even on shutdown time). One may add IP addresses and remove these one added, but not more.

Running a DHCP client on a DIFFERENT interface may cause havoc if there was a default route, nameserver, etc. configured on the original (nfs) interface too.

Task: implement some bulletproofing so that nfsroot configurations can be cleanly booted and shut down, without having to do additional configurations. Use the .config stuff like FWRT_TARGET_ROOTFS_NFS.

Communication was:

- we must ensure that eth0 (or whatever interface the kernel uses) isn't

listed in /etc/network/interfaces, which is automatically generated

- maybe fold fwifupdown into base-files - for failsafe configuration, do more stuff in preinit.arch
