[OpenJDK 2D-Dev] RFR: 8225007: java/awt/print/PrinterJob/LandscapeStackOverflow.java may hang

[Phil Race]

Bug : https://bugs.openjdk.java.net/browse/JDK-8225007
Webrev : http://cr.openjdk.java.net/~prr/8225007/

This is just adding the printer keyword to two jtreg tests.
This is useful for both selecting & excluding the tests and should prevent
one of these tests from hanging in our nightly headful testing.
