export-object: Recover public key from algorithm specific attributes

Some tokens such as SoftHSMv2 omits CKA_PUBLIC_KEY_INFO when it can be derived from algorithm specific attributes, such as CKA_MODULUS and CKA_PUBLIC_EXPONENT for RSA. This adds support for it if libtasn1 is available at compile time. Signed-off-by: Daiki Ueno <[email protected]>
