Improve adbe.pkcs7.sha1 signature verification distro/collabora/co-24.04

For PDF signatures with SubFilter == adbe.pkcs7.sha1, we only
compared hash values and never actually checked SignatureValue
within SignerInfo.

Fix bugs introduced by 055fd58711d57af4d96214aebd71b713303d5527 and
e58ed17e35989350afe3e9fd77b24515df782eac by verifying the actual
(public-key) signature after the hash values compare equal.
