Fix PKINIT CMS error checking for older OpenSSL

Fix PKINIT CMS error checking for older OpenSSL

Commit 70f61d417261ca17efe3d60d180033bea2da60b0 updated the
CMS_verify() error code checks, using two error codes new to OpenSSL
3.0 (RSA_R_DIGEST_NOT_ALLOWED and CMS_R_UNKNOWN_DIGEST_ALGORITHM).
This change broke the build for OpenSSL 1.0 and 1.1.

Instead of looking for codes indicating an algorithm issue and
assuming that everything else is an invalid signature, check for the
code indicating an invalid signature and assume that everything else
is an algorithm issue.
