RFR: 8266456: Replace direct TKit.run() calls with jdk.jpackage.test.Annotations.Test annotation [v2]

[Alexander Matveev]

> - Replaced direct TKit.run() calls with Test annotation.
>  - Increased timeout for SigningPackageTest from default to 360 due to timeout. This is regression from JDK-8248904 due to changes done in signing and --remove-signature adds additional time since it is run per file.
>  - Fixed issue with jtreg.SkippedException which caused test to fail instead of being skipped, since it was wrapped in ExceptionBox.
