givaro: backport gcc-13 build fix

Without the change `givaro` build on `gcc-13` fails as:

    /givaro/givdegree.h:42:33: error: 'uint64_t' does not name a type
      42 |         Degree operator*( const uint64_t& e) const { return Degree(_deg*e); }
         |                                 ^~~~~~~~
    /givaro/givdegree.h:23:1: note: 'uint64_t' is defined in header '<cstdint>'; this is probably fixable by adding '#include <cstdint>'
      22 | #include <iostream>
