QGtkStyle: fix a warning

Commit c0893962ef94f12594f936ef2a50db6d0328eca0 added two
definitions of a variable named gtkToggleButtonStyle in nested
scopes. Because of name lookup rules, the second one wasn't
initialised with the first one, but with itself.

This leaves the second gtkToggleButtonStyle uninit'ed.

Simply remove the surplus declaration, leaving the name to
the original declaration.
