libstdc++: Simplify chrono::duration::_S_gcd

We can simplify this constexpr function further because we know that
period::num >= 1 and period::den >= 1 so only the remainder can ever be
zero.

libstdc++-v3/ChangeLog:

* include/std/chrono (duration::_S_gcd): Use invariant that
neither value is zero initially.
