(struct cdf_object_s): Replace fields image and imagelen by cert.
(struct prkdf_object_s): Add extusage flags
(send_keypairinfo): Use them.
(cdf_object_from_certid): Factor parts out to ...
(cdf_object_from_objid): new function.
(read_ef_prkdf): Move info printing to ...
(read_p15_info): here.  Fill the extusage flags.

This allows us to return only KEYPAIRINFO lines for keys we can
actually use.
