secret: Adjust logic to build file path in secretLoad

The 'secretLoad' was essentially open coding virFileBuildPath.

Adjust the logic to have the caller build the path and pass it. The net
sum of ignoring the virFileBuildPath failure is the same as before where
the failure to virAsprintf the path would have been ignored anyway in
the secretLoad error path.
