math/givaro: fix build with clang 19
Clang 19 has become more strict about errors in member functions, which
results in errors building math/givaro:
./givaro/givaro/givaro/random-integer.h:94:51: error: no viable overloaded '='
94 | const_cast<Integer_Domain&>(_ring)=R._ring;
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~
./givaro/givaro/givaro/random-integer.h:94:51: note: type 'Integer_Domain' (aka 'ZRing<Integer>') is incomplete
94 | const_cast<Integer_Domain&>(_ring)=R._ring;
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~

| ^The const_cast line has been removed by upstream as part of
https://github.com/linbox-team/givaro/commit/b0cf33e1, but that commit
is rather large. It is enough to only delete the line.
Also fix a failure that occurs when running "make test":
../src/kernel/recint/rfiddling.h:170:29: error: no member named 'Low' in 'rint<K>'
This is because the expression max.Low.Value should actually be
max.Value.Low.
