Change std f32 test to pass under Miri

Adds `APPROX_DELTA` to 2 tests of `f32::log` reported in [#miri > Miri test-libstd Failure (2025-08)](https://rust-lang.zulipchat.com/#narrow/channel/269128-miri/topic/Miri.20test-libstd.20Failure.20.282025-08.29).

I changed 2 lines, the first one is the actual failure. The second one is precautionary.
