treewide: remove scaled from phoc.ini

Removes the scaled key from phoc.ini, as this should be fixed upstream and not hacked in downstream configs. Most devices should work with the default scaling configuration.

If your device has been changed, we would greatly appreciate if you could install wlr-randr $ sudo apk add wlr-randr, and add the output to https://pad.riseup.net/p/phosh-scales-keep:

$ wlr-randr
$ cat /sys/firmware/devicetree/base/compatible
