touchscreen: Respect list item selection size
Some lists have tall items that span more than one line of text,
eg. the bookmark menu or ID3 tag menu. The touchscreen code didn't
handle these menus correctly and touching on the lower part of a
list item could select "between" two items, leading to incorrect
rendering and behavior due to callers relying on the selected item
being properly aligned to the selection size. Fix this by ensuring
the touch code only generates properly aligned selections.
