signapi: expose metadata format and key

Explicitly expose functions for querying the metadata format
and key name used by OstreeSign object:
 - ostree_sign_metadata_format
 - ostree_sign_metadata_key

This allows to use the same metadata format and key name
by 3-rd party applications using signapi.
