panicf: Clear backdrop and print with black font on white background to prevent possible difficulties with reading it (especially on cabbiev2). Also start printing in the second row and column.

This fixes the second part of FS#10503 - "Menu and WPS backdrop not cleared when shutting down or during panic" (the first part is not a bug imo),
