[jdk17] RFR: 8271169: runtime/Safepoint/TestAbortVMOnSafepointTimeout.java can be run in driver mode

[Igor Ignatyev]

Hi all,

could you please review this small and trivial test-only patch?
from JBS:
> `runtime/Safepoint/TestAbortVMOnSafepointTimeout.java` uses `main/othervm` so `TestAbortVMOnSafepointTimeout` is run w/ the flags required for WhiteBox API, yet `TestAbortVMOnSafepointTimeout` doesn't use WhiteBox API and can be run in driver mode.

testing: `runtime/Safepoint/TestAbortVMOnSafepointTimeout.java` on `{linux,windows,macos}-x64`

Thanks,
-- Igor
