Inside portdbapi._metadata_callback(), preserve _eclasses_ when the EAPI is

unsupported since the eclass timestamps might be needed in order to decide
that the cache entry should be regenerated. Also, make sure that all metadata
returned from portdbapi.aux_get() is returned as empty strings when the
EAPI is unsupported.
