ar7-2.4 cleanup

 - Switch to generic init scripts (/sbin/mount_root, /bin/firstboot, 
   /etc/preinit), failsafe part moved to /etc/preinit.arch.
   This should fix #1449 with an added benefit of using mini_fo.
 - Switch to generic /etc/config/network.
 - ar7 flashmap: change "OpenWrt" to "rootfs_data", move ar7_mtd_cleanup
   out of .exit.
