Reposition the goog.ui.ComboBox menu whenever it might be shown.

This fixes a bug where, if the menu is anchored above the input box
(such as when the input box is at the bottom of the page),
subsequent filtering of the menu would cause the bottom of the menu
to grow upwards instead of the top of the menu to grow downwards.
