* include/bits/random.h (chi_squared_distribution::param): Update
gamma distribution parameter.
* testsuite/26_numerics/random/chi_squared_distribution/83833.cc: New
test.
Tested powerpc64le-linux, committed to trunk.
(I know this is not a regression, but it's a small fix, and I also
plan to apply it on the branches).
This is needed to prevent the test failing on x86-32.
Committed to trunk and gcc-7-branch.
