Wrong folder and file permissions

[schuettecarsten]

I ran into openwrt/openwrt#18664 and we found out that the permissions of /etc and other files are modified by something. This is caused by the files copied from /files to the image. These files are the files from this repo. So, please change permissions of folders to 755 (is 775) and files to 644 (is 775).

Also, the scripts etc/init.d/dscpclassify and etc/hotplug.d/iface/21-dscpclassify shoud be +x.
