Add back 'WS_VSCROLL' flag when creating a combobox window. Without it, the dropdown list of a combobox longer than the 'default'(?) size gets truncated instead of getting a scrollbar.
Add back 'WS_VSCROLL' flag when creating a combobox window. Without it, the dropdown list of a combobox longer

BUG=13438 (http://crbug.com/13438)
TEST=In Options | Under the hood, click  'Fonts & languages' button. The default encoding menu should have a scrollbar. In languages tab, Chrome UI language list contains 49 languages instead of 20(?) or so languages.
In a shorter dropdown list (e.g. spellcheck language dropdown), there should be no scrollbar.
