[Buildroot] [PATCH 2025.02.x] package/sqlite: backport patch for CVE-2026-1182{2, 4}

- CVE-2026-11822:
    SQLite before 3.53.2 contains memory corruption vulnerabilities in the
    FTS5 full-text search extension that allow attackers to cause process
    crashes, memory exhaustion, or arbitrary code execution by supplying a
    crafted database with malformed FTS5 page data. Attackers can trigger
    an out-of-bounds read in fts5LeafSeek() via an attacker-controlled
    loop bound and a heap buffer overflow write in fts5ChunkIterate()
    through a crafted continuation page causing an integer underflow,
    exploitable when an FTS5 MATCH query is executed against the malicious
    database.

- CVE-2026-11824:
    SQLite before 3.53.2 contains a heap-based buffer overflow
    vulnerability in the FTS5 full-text search extension that allows
    attackers to cause a crash or execute arbitrary code by supplying a
    crafted database with malicious continuation page metadata specifying
    a szLeaf value smaller than 4. Attackers can trigger an integer
    underflow in fts5ChunkIterate() causing an inflated remaining byte
    count during FTS5 MATCH query processing, leading to a heap buffer
    overflow of attacker-controlled data in applications compiled with
    SQLITE_ENABLE_FTS5.
