event_handle_configurerequest: Add missing test 

c->size_hints.win_gravity only contains something valid if the
XCB_ICCCM_SIZE_HINT_P_WIN_GRAVITY bit is set in the flags. Most likely
this wasn't noticed before, because most code just happens to
zero-initialize this field and gravity 0 is NorthWest, which does not do
anything.
