scripts/kvm/kvm_stat: Fix tracefs access checking
On kernels build without CONFIG_TRACING kvm_stat will bail out even
when traces are not used. This is not very helpful, especially if the
user can't install a new kernel. Instead, we should warn the user and
fall back to debugfs statistics.
These changes check if trace statistics were selected without kernel
support, warn with a small timeout, set the debugfs statistics option
to True and the tracefs one to False.
Fixes: 7aa4ee5 ('scripts/kvm/kvm_stat: Improve debugfs access checking')
