[jdk17] RFR: 8269281: java/foreign/TestUpcall.java times out

[Maurizio Cimadamore]

The previous fix to this test which used removed the `VerifyDependency` flag worked well, but we're still observing rare timeouts. Looking at the test reports, it seems likely that slightly increasing the timeout would do the trick.
