KVM: arm64: selftests: Disable single-step with correct KVM define



Disable single-step by setting debug.control to KVM_GUESTDBG_ENABLE,
not to SINGLE_STEP_DISABLE.  The latter is an arbitrary test enum that
just happens to have the same value as KVM_GUESTDBG_ENABLE, and so
effectively disables single-step debug.

No functional change intended.
