fix: convert cdn-cache Makefile to standard LuCI.mk format

Simplified luci-app-cdn-cache Makefile to use standard LuCI.mk template
instead of custom Package definition. This allows the package to build
correctly with the local-build.sh script and SDK.

The luci.mk template automatically handles installation of files from
the root/ and htdocs/ directories, so custom install directives are
not needed.
