DateInfo: Fix timeToStringWithFormat buffer length

strftime places a NULL-terminated string in the buffer, so the std::string
buffer needs to be resized to not include the terminator character
(or anything after it).

Without this fix, modification dates in altered PDF documents (such as when
adding a digital signature) are not truncated properly, instead padding
the date with a null byte and extra spaces until the end of the buffer is
reached. This bad syntax compromises the ability to verify the signature
with other applications, but the Poppler signatory has no indication of this.

Subject: [PATCH] Limit ammount of annots per document/page

Gbp-Pq: Name CVE-2025-52886.patch

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.
