This adds an unused parameter, but lets us get rid of this new warning
with gcc 8:
virt-viewer-window.c: In function 'get_image_format':
virt-viewer-window.c:930:33: warning: cast between incompatible function types from 'GHashTable * (*)(void)' {aka 'struct _GHashTable * (*)(void)'} to 'void * (*)(void *)' [-Wcast-function-type]
g_once(&image_formats_once, (GThreadFunc)init_image_formats, NULL);
