GtkFileChooserButton: Don't update icon/label so often

Browse Source 
They were updated in style-changed, causing the label to get set to
(None), then to the actual file name again a frame later, both of the
updates cause the GtkFileChooserButton to resize, possibly to the
minimal width, causing the layout to jump. Fix this by only updating
icon/label in style-updated when the icon theme actually changed, which
is the only case we care about here.
