vfio: selftests: Extend timeout for runner executions
When executed via the runner, ie. run_kselftest.sh, tests are subject
to a default 45s timeout. None of the igb, ioatdma, or nv_falcon
drivers can run the vfio_pci_driver_test within this window.
The igb driver is the worst due to the device getting wedged from bad
DMAs in mix_and_match and requiring the full transaction pending
delay prior to FLR.
This is even further exacerbated when the system implements
firmware-first error handling and the transaction pending scheduled
delays are preempted beyond expectations by SMIs.
Worst case observed runtime for the whole vfio_pci_driver_test on
such a setup is 450s. Round up to 600s.
