Updated Java keys for cross-platform tests and removed them from known failures

[kpumuk]

The truststore and keystore were regenerated using keys in test/keys:

# keytool does not support "replace" operation:
keytool -delete \
    -alias localhost \
    -keystore lib/java/src/crossTest/resources/.truststore \
    -storepass thrift
keytool -import \
    -alias localhost \
    -file test/keys/CA.pem \
    -keystore lib/java/src/crossTest/resources/.truststore \
    -storepass thrift

# server keystore
keytool -importkeystore \
    -srckeystore test/keys/server.p12 \
    -srcstoretype PKCS12 \
    -srcstorepass thrift \
    -destkeystore lib/java/src/crossTest/resources/.serverkeystore \
    -deststoretype pkcs12 \
    -deststorepass thrift

# client keystore
keytool -importkeystore \
    -srckeystore test/keys/client.p12 \
    -srcstoretype PKCS12 \
    -srcstorepass thrift \
    -destkeystore lib/java/src/crossTest/resources/.clientkeystore \
    -deststoretype pkcs12 \
    -deststorepass thrift

Java tests were updated to use separate keystores for client and server.

• Did you create an Apache Jira ticket? (Request account here, not required for trivial changes)
• If a ticket exists: Does your pull request title follow the pattern "THRIFT-NNNN: describe my issue"?
• Did you squash your changes to a single commit? (not required, but preferred)
• Did you do your best to avoid breaking changes? If one was needed, did you label the Jira ticket with "Breaking-Change"?
• If your change does not involve any code, include [skip ci] anywhere in the commit message to free up build resources.
