    [SPARK-27178][K8S] add nss to the spark/k8s Dockerfile
    
    ## What changes were proposed in this pull request?
    
    while performing some tests on our existing minikube and k8s 
infrastructure, i noticed that the integration tests were failing. i dug in and 
discovered the following message buried at the end of the stacktrace:
    
    ```
      Caused by: java.io.FileNotFoundException: /usr/lib/libnss3.so
        at sun.security.pkcs11.Secmod.initialize(Secmod.java:193)
        at sun.security.pkcs11.SunPKCS11.<init>(SunPKCS11.java:218)
        ... 81 more
    ```
    after i added the `nss` package to 
`resource-managers/kubernetes/docker/src/main/dockerfiles/spark/Dockerfile`, 
everything worked.
    
    this is also impacting current builds.  see:  
https://amplab.cs.berkeley.edu/jenkins/job/testing-k8s-prb-make-spark-distribution-unified/8959/console
    
    ## How was this patch tested?
    
    i tested locally before pushing, and the build system will test the rest.
    
    Closes #24111 from shaneknapp/add-nss-package-to-dockerfile.
