RFR: 8300405: Screen capture for test JFileChooserSetLocationTest.java, failure case [v2]

[Tejesh R]

> This is a diagnostic update related to [JDK-8295804](https://bugs.openjdk.org/browse/JDK-8295804). The issue was not reproducible and was showing up in particular machines (Where the machines are down now). So adding a screen capture to `BufferedImage` in case of failure so that it will help in analysis when the issue comes up in future.

Tejesh R has updated the pull request incrementally with one additional commit since the last revision:

  Updated screen capture bounds
