[MJAVADOC-652] - Dependencies on the patch-module path

[philsmart]

Add parameter to turn off support for the module path even if supported by the environment.

To bypass module-path and patch-module-path arguments from being created for Javadoc even if using Java 9 and your project declares support for modules e.g. includes an automatic module name.

Following this checklist to help us incorporate your
contribution quickly and easily:

• https://issues.apache.org/jira/browse/MJAVADOC-652
• Each commit in the pull request should have a meaningful subject line and body.
• Format the pull request title like [MJAVADOC-XXX] - Fixes bug in ApproximateQuantiles,
  where you replace MJAVADOC-XXX with the appropriate JIRA issue. Best practice
  is to use the JIRA issue title in the pull request title and in the first line of the
  commit message.
• Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
• Run mvn clean verify -Prun-its to make sure basic checks pass. A more thorough check will
  be performed on your pull request automatically.

Please add example project to IT test with twice executions - one without and one with new parameter.
you can prepare invoker.properties

invoker.goals.1 = ...
invoker.buildResult.1 = failure

invoker.goals.2 = ... -DdisableModulePath=true
invoker.buildResult.2 = success

[philsmart]

I added the test project. However, both testing conditions will return success. The build is not actually failing (in the test project); you need to inspect the Javadoc @options file to see the patch-module discrepancy (which is causing a problem in a much larger project I work on).

[slawekjaranowski]

It is not good that we can't reproduce problem in test project ...
We must find a way to reproduce, in other case that is a probability that problem is somewhere else.

[philsmart]

The issue of it using the patch-module path is reproducible in the test project. But I will see if I can get it to fail during the Javadoc construction

[rfscholte]

there should be no need for this extra parameter
