[jdk11u-dev] RFR: 8282538: PKCS11 tests fail on CentOS Stream 9

[Olga Mikhaltsova]

It's backport of JDK-8282538 to jdk11u.
The same failure of the regression tests group (test/jdk/sun/security/pkcs11/Signature/) is observed on CentOS Stream 9 because of missing cert9.db and key4.db which are required by NSS 3.35 and above.
cert9.db and key4.db were copied from another location of the repository test/jdk/sun/security/pkcs11/Secmod/.
Tested with tier2 on CentOS Stream 9.
