JDK-8176482: Use of DirectiveVisitor needs @DefinedBy annotation for RunCodingRules.java

[joe darcy]

Hello,

*sigh*

Sometimes it pays to run all the test, even ones where there is no way 
they could fail!

The patch below correct an oversight in the recently-pushed 8176477: 
"Use DirectiveVisitor to print module information" which neglected to 
include the @DefinedBy annotation it is use of the DirectiveVisitor type.

Thanks,

-Joe
