This was a design decision from the UI design team [1], and it's
implemented at the theme level (by drawing these borders inside the
actual GtkButton and other widgets). There's nothing you can do to get
rid of these margins. Rationale is that doing it this way, UI team could
make sure that all apps "get the padding right".

There's a bug about the lack of proper documentation of this in
bugs.maemo.org (https://bugs.maemo.org/show_bug.cgi?id=5458).
