KVM: selftests: Sync perf_test_args to guest during VM creation
Copy perf_test_args to the guest during VM creation instead of relying on
the caller to do so at their leisure. Ideally, tests wouldn't even be
able to modify perf_test_args, i.e. they would have no motivation to do
the sync, but enforcing that is arguably a net negative for readability.
No functional change intended.
[Set wr_fract=1 by default and add helper to override it since the new
access_tracking_perf_test needs to set it dynamically.]
