RFR[14] JDK-8180837: SunPKCS11-NSS tests failing with CKR_ATTRIBUTE_READ_ONLY and CKR_MECHANISM_PARAM_INVALID

Hi,
Tests sun/security/pkcs11/Secmod/AddTrustedCert.java and 
sun/security/pkcs11/tls/TestKeyMaterial.java failed due to some changes 
in NSS.
This fix just workarounds this problem. For more details, please see the 
comments in this JBS issue.
And it also provides a pre-built NSS libs for linux-x64 platform. Then, 
the PKCS11 tests won't depend on the system built-in NSS libs in our CI 
on this platform.
