Headers: give _Unwind_Control_Block double-word alignment
The C++ ABI requires that the exception object (which under AEABI is the
`_Unwind_Control_Block`) is double-word aligned. The attribute was
applied to the `_Unwind_Exception` type, but not the
`_Unwind_Control_Block`. This should fix the libunwind test for the
alignment of the exception type.
