Fix expm1f overflow threshold 
Due to an erroneous overflow threshold, `expm1f` was incorrectly
returning `inf` for inputs in the range `[88.72169, 88.72283]`. This
additionally caused `sinhf` to return `NaN` for inputs in that range.

The bug was ported from the original in musl, which has since been fixed
in [1].
