HADOOP-19719. Wildfly Followup: TestDelegatingSSLSocketFactory (#8075) (#8071)

Downgrade to a skipped test if the attempting to create an openssl factory
raises a wrapped NoSuchAlgorithmException; this is to avoid failures on test
runs on RHEL8 VMs.

Note: this branch-3.4 version preserves the test testJSEENoGCMJava8().
