Drop support for custom |mod_exp| hooks in |RSA_METHOD|.

The documentation in |RSA_METHOD| says that the |ctx| parameter to
|mod_exp| can be NULL, however the default implementation doesn't
handle that case. That wouldn't matter since internally it is always
called with a non-NULL |ctx| and it is static, but an external
application could get a pointer to |mod_exp| by extracting it from
the default |RSA_METHOD|. That's unlikely, but making that impossible
reduces the chances that future refactorings will cause unexpected
trouble.
