RFR: 8352419: Test tools/jpackage/share/ErrorTest.java#id0 and #id1 fail [v2]

[Alexey Semenyuk]

> Make tools/jpackage/share/ErrorTest.java test safely handle the case when native bundling is unavailable on the test host.
> 
> Additionally:
>  - If native bundling is unavailable on the test host, PackageTest will throw `jtreg.SkippedException` and mark the test as skipped instead of silently doing nothing. This should mark a few jpackage tests "skipped" in tests runs on Alpine Linux that doesn't support either .deb or .rpm packaging.
>  - Get rid of the dependency on `jtreg.SkippedException` from `/jdk/test` lib as this exception can be thrown from almost every jpackage test because of the changes in PackageTest. Instead embed `jtreg.SkippedException` classfile in TKit.java source and load it from there. This is a less intrusive alternative to adding 
> 
>  * @library /test/lib
>  * @build jtreg.SkippedException
> 
> in every jtreg test declaration
