RFR: 8259319: Illegal package access when SunPKCS11 requires SunJCE's classes [v2]

[Martin Balao]

> As described in JDK-8259319 [1], this fix proposal is to set proper access permissions so the SunPKCS11 provider can create instances of SunJCE classes when a Security Manager is installed and the fallback scheme is used.
> 
> No regressions found in jdk/sun/security/pkcs11 tests category.
>
