S1Angle::SinCos broken on ubuntu 22

I tried to enable the test workflow for ubuntu 22 and get a failure due to `sincos`.

```
/home/runner/work/s2geometry/s2geometry/src/s2/s1angle_test.cc:139: Failure
Expected equality of these values:
sin_cos.cos
Which is: -0.2[58](https://github.com/google/s2geometry/actions/runs/13603572823/job/38032416706?pr=412#step:8:59)81904510251996
cos(angle)
Which is: -0.25881904510251991

I will disable `sincos` for glibc until we can narrow this down further.
