`TEST=serviceability/sa/TestJhsdbJstackMixedWithVDSOCallCore.java` fails if
`/lib/modules/<version>/vdso/vdso64.so` is missing. (Seems that is the case on
default Debian installation.)

I could reproduce same problem on WSL 2 (kernel
6.6.87.2-microsoft-standard-WSL2). The test should be skipped if vDSO library
not found.
