COPKGManager: use general options for cache, temp dir and logging

cache dir option not required assigned in config file.

Note: existing option "cache" in opkg config file must be removed now, otherwise
it could hail error log messages and gui package listing could be garbled!
Not nice now, but it's one step for an unified configure handling.
