Fix #2101821: Cut labels of menu items in "SnapTell" market app.

Ummmm...  this turns out to be pretty bad.  NinePatchDrawable was not
scaling its reported padding for compatibility mode, causing spacing
to be off.  All over the place.  This change should improve things quite
a bit (and magically makes nearly all of the menu flaws go away).
