tools/sched_ext: scx_userland: fix data races on shared counters
The stats thread reads nr_vruntime_enqueues, nr_vruntime_dispatches,
nr_vruntime_failed, and nr_curr_enqueued concurrently with the main
thread writing them, with no synchronization.
Use __atomic builtins with relaxed ordering for all accesses to these
counters to eliminate the data races.
Only display accuracy is affected, not scheduling correctness.
