c-b: Export inverse hyperbolic trigonometric functions

Since a1feab16381b ("Use libm for acosh and asinh"), the standard library may link these functions to get a more accurate approximation; however, some targets do not have the needed symbols available. Add them to the compiler-builtins export list to make sure the fallback is usable.

Closes: rust-lang/rust#154919
