Subject: 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. (trunk r12330)
