RFR: 8325038: runtime/cds/appcds/ProhibitedPackage.java can fail with UseLargePages

[Calvin Cheung]

A simple test fix by not checking the `[cds]` tag in the output because the tag may have spaces if there's other log output message with longer log tag before it.

Tested manually with `-XX:+UseLargePages`.
