RFR: 8233685: Test tools/javac/modules/AddLimitMods.java fails

[Jan Lahoda]

The ToolBox' JavaTask by default picks up content of system property "test.java.opts". In the case of this bug,
test.java.opts contains "-XX:+FlightRecorder". And one of the sub-tests (testRuntime2Compile) of the AddLimitMods test
tries to invoke the java launcher with "--limit-modules java.base", and this fails because flight recorder cannot start.

The proposal is to avoid using the content of test.java.opts for that test.
