S60Style's tab widget is too small for touch use

TabWidget for S60Style is too small for touch use, it is rather hard to
accurately touch the tabpane to switch the active tab.
To fix this, we ask the native tabpane height from AVKON and set the
QTabWiget's pane height to native height (or bigger).
