qemu_tpm: Try harder to create emulator state

Browse Source 
If a per-domain SWTPM state directory exists but is empty our
code still considers it a valid state and skips running
'swtpm_setup' (handled in qemuTPMEmulatorRunSetup()).
While we should not try to inspect individual files created by
swtpm, we can still consider empty folder as non-existent state.
