KVM: selftests: Always run vCPU thread with blocked SIG_IPI
The main thread could start to send SIG_IPI at any time, even before signal
blocked on vcpu thread. Therefore, start the vcpu thread with the signal
blocked.
Without this patch, on very busy cores the dirty_log_test could fail directly
on receiving a SIGUSR1 without a handler (when vcpu runs far slower than main).
