Propagate selection all the way on key export

EVP_PKEY_eq() is used to check, among other things, if a certificate
public key corresponds to a private key. When the private key belongs to
a provider that does not allow to export private keys this currently
fails as the internal functions used to import/export keys ignored the
selection given (which specifies that only the public key needs to be
considered) and instead tries to export everything.

This patch allows to propagate the selection all the way down including
adding it in the cache so that a following operation actually looking
for other selection parameters does not mistakenly pick up an export
containing only partial information.
