Properly verify adbe.pkcs7.sha1 signatures.
For signatures with non-empty encapsulated content
(typically adbe.pkcs7.sha1), we only compared hash values and
never actually checked SignatureValue within SignerInfo.
The bug introduced by
c7c0207b1cfe49a4353d6cda93dbebef4508138f
made trivial signature forgeries possible. Fix this by calling
NSS_CMSSignerInfo_Verify() after the hash values compare equal.
