libboost-numeric-ublas: Patch downstream/

With -DNDEBUG BOOST_UBLAS_INLINE actually expands to `inline` causing
instances of the following code to be a syntax error:

 BOOST_UBLAS_INLINE
 template<class size_type, class layout_type>

This bug has already been reported upstream at
boostorg/ublas#82. It has been fixed in the
`develop` branch but not released yet.
