RFR: JDK-8229840: Add jtreg test for --linux-app-category option

[Alexey Semenyuk]

Please review the jpackage fix for bug [1] at [2].

This is a fix for the JDK-8200758-branch branch of the open sandbox 
repository (jpackage).

- added jtreg test for --linux-app-category option;
- added jtreg test for --linux-release option; This is to address [3] issue;
- introduced helper classes to simplify adding new jtreg tests. The 
helper classes allow to avoid code duplication between platform specific 
jpackage jtreg tests. They also allow to log actions taken by tests.
