Register sun.security.provider.NativePRNG#<init> for reflection

When instantiating a SecureRandom the constructor reflectively looks for
the NativePRNG constructor and invokes it.

Although the lookup succeeds without the explicit registration, it's
better to explicitly request it. This also prevents getting a
`MissingRegistrationError` when using
`-H:+ThrowMissingRegistrationErrors` or `--exact-reachability-metadata`.
