Made meta.yaml test find services directory without hard-coded providerName

[melinath]

Fixes b/474729931. Prior to #16102 this wasn't causing problems because the test would only fail if there were values returned as "unknown" from the cache - but if the cache couldn't be loaded at all we would instead return "failed_to_populate_metadata_cache".
