libopkg: initialize conffile list during status parsing

When parsing conffile information from status files, we need to initialize
the conffile list head upon encountering a "Conffiles:" line, otherwise
parse_conffiles() will ignore all subsequent entries due to a missing list
pointer.

Fixes missing conffile information in /usr/lib/opkg/status on a fresh
installation.
