Minor incompat fix for GtkFrame properties

[Owen Taylor <otaylor redhat com>]

Just checked this in:

	* gtk/gtkframe.c (gtk_frame_class_init): label_xalign
	and label_yalign need to be float properties to
	correspond to GTK+-1.2, to gtk_frame_set_label_align,
	and to the types of the xalign and yalign properties of GtkMisc.
	(#63484, Vitaly Tishkov)

If you added a call to g_object_get() on "label_xalign" or
"label_yalign" properties between the point GtkFrame was converted to
use GObject properties and now, then you need to fix the type of
the variable you pass in. 

This most likely affects absolutely nobody.
