rootfs.py, package_manager.py, sdk.py: Fix building from feeds feature for opkg

When using opkg as the PM backend, one has the option to provide custom
feeds to create the rootfs from.

This commit:
 * fixes this in the refactored code;
 * moves the custom config creation code to python;
 * clean up the package-ipk.bbclass;
