RFR: 8378561: Mark gc/shenandoah/compiler/TestLinkToNativeRBP.java as /native

[SendaoYan]

Hi all,

Test test/hotspot/jtreg/gc/shenandoah/compiler/TestLinkToNativeRBP.java invoke `System.loadLibrary("LinkToNativeRBP")` staticly. I think it will be better to mark this test as /native, since jtreg will deny run the test without -nativepath paramater.

Change has been verified by run this test locally, trival fix, no risk.
