  sdl: Fix widget_id truncation in widget lookup functions

get_widget_pointer_from_id() and get_widget_pointer_from_main_list()
still used Uint16 id parameters after MAX_ID and widget_id were
widened to 32 bits in 7a187ce264. This caused silent truncation of
IDs like (MAX_ID - 1000 - style), making lookups fail and return
NULL, leading to a segfault in nation_button_callback.
