RFR: 8366359: Test should throw SkippedException when there is no lpstat [v2]

[SendaoYan]

> Hi all,
> 
> I think test javax/print/PrintServiceLookup/CountPrintServices.java should throw jtreg.SkippedException when there is no lpstat, rather that report test failure.
> 
> Only javax/print/PrintServiceLookup/CountPrintServices.java invokes lpstat explicitly.

> Change has been verified locally, test-fix only, no risk.
