RFR: 8282538: PKCS11 tests fail on CentOS Stream 9

[Olga Mikhaltsova]

I would like to add cert9.db and key4.db to /test/jdk/sun/security/pkcs11/nss/db/ to fix the PKCS11 tests failure on CentOS Stream 9.
Starting from NSS 3.35 cert9.db and key4.db files may be targeted instead of cert8.db and key3.db.
In case of CentOS Stream 9 the lowest available version of NSS for downgrade is 3.67 and cert9.db, key4.db are targeted.
