[3.14] Fix a compiler warning in _randommodule.c (GH-141058) (#141063)

Fix a compiler warning in _randommodule.c (GH-141058)

The test just before the cast ensures that the cast cannot overflow.

Fix the warning on 32-bit Windows:

    Modules\_randommodule.c(525,28): warning C4244: '=': conversion
    from 'uint64_t' to 'Py_ssize_t', possible loss of data
(cherry picked from commit 4ac16dd10950fad2d3e58e8b0ba5f2e621af3cc1)
