Fix D-Bus path for single-host POST code snoop

phosphor-post-code-manager was already updated to watch for POST code
updates at Raw0, which broke POST code monitoring on single-host
configurations. While the full change for multi-host support is still in
progress, this allows the single-host usage to continue working.

Tested: With changes
phosphor-post-code-manager: I59ed514f28c2bb9b159f51367c38557bf55bf226
bmcweb: I2fdf97b7aaf8d6471d162f8ed1b72143491ac23f
Power cycled host and verified that new POST codes are added under
/redfish/v1/Systems/system/LogServices/PostCodes/Entries.
